Chapter 11: Activity 3 (Spongebob Activity) And Activity 4 And 5 (Punnet Squares) Flashcards

It's strange why-- 16 combinations. So this is what blending is. Well, which of these are homozygous dominant? H. Cheaper products are better. Let me write this down here. When the mom has this, she has two chromosomes, homologous chromosomes. Geneticist Reginald C. Punnet wanted a more efficient way of representing genetics, so he used a grid to show heredity. Since your father can only pass a "b", your eye color will be completely determined by whether your mom gives you her "B" or her "b". Worked example: Punnett squares (video. Actually, we could even have a situation where we have multiple different alleles, and I'll use almost a kind of a more realistic example. So, the dominant allele is the allele that works and the recessive is the allele that does not work. Two lowercase t's-- actually let me just pause and fill these in because I don't want to waste your time. Big teeth and brown eyes.

Which Of The Genotypes In #1 Would Be Considered Purebred Golden Retriever

And these are called linked traits. And so then you have the capital B from your dad and then lowercase b from your mom. So if I said if these these two plants were to reproduce, and the traits for red and white petals, I guess we could say, are incomplete dominant, or incompletely dominant, or they blend, and if I were to say what's the probability of having a pink plant? So brown eyes and little teeth. And then the final combination is this allele and that allele, so the blue eyes and the small teeth. Which of the genotypes in #1 would be considered purebred morab horse association. Your mother could have inherited one small b and still had brown eyes, and when she had you, your father passed on a little b, and your mother passed on her little b, and you ended up with blue eyes.

Which Of The Genotypes In #1 Would Be Considered Purebred If The Number

So what's the probability of having this? That's what AB means. Well, both of your parents will have to carry at least one O. Which of the genotypes in #1 would be considered purebred golden retriever. So hopefully, in this video, you've appreciated the power of the Punnett square, that it's a useful way to explore every different combination of all the genes, and it doesn't have to be only one trait. Very fancy word, but it just gives you an idea of the power of the Punnett square. What you see is brown eyes.

Which Of The Genotypes In #1 Would Be Considered Purebred If X

For example, you could have the situation-- it's called incomplete dominance. How is it that sometimes blonde haired people get darker hair as they get older? Which of the genotypes in #1 would be considered purebred for a. Something's wrong with my tablet. Products are cheaper by the dozen. So the different combinations that might happen, an offspring could get both of these brown alleles from one copy from both parents. Learn how to use Punnett squares to calculate probabilities of different phenotypes.

Which Of The Genotypes In #1 Would Be Considered Purebred Morab Horse Association

Well examining your pedigree you'd find out that at least one of your relatives (say your great grandmother) had blue eyes "bb", but when they had a kid with your "BB" brown great-grandfather, the children were heterozygous (one of each allele) and were therefor "Bb". So let's draw-- call this maybe a super Punnett square, because we're now dealing with, instead of four combinations, we have 16 combinations. So let's go to our situation that I talked about before where I said you have little b is equal to blue eyes, and we're assuming that that's recessive, and you have big B is equal to brown eyes, and we're assuming that this is dominant. Let me do it like that. Created by Sal Khan. So this is what's interesting about blood types. And the phenotype for this one would be a big-toothed, brown-eyed person, right? Let me just write it like this so I don't have to keep switching colors.

Which Of The Genotypes In #1 Would Be Considered Purebred Yearling Halter Ath

In his honor, these are called Punett Squares. I think England's one of them, and you UK viewers can correct me if I'm wrong. It's actually a much more complicated than that. If you're talking about crossing two hybrids, this is called a monohybrid cross because you are crossing two hybrids for only one trait. What are the chances of you having a child with blue eyes if you marry a blue-eyed woman? You have a capital B and then a lowercase b from that one, and then a capital T from the mom, lowercase t from the dad. So if you have either of these guys with an O, these guys dominate.

Which Of The Genotypes In #1 Would Be Considered Purebred For A

This will typically result in one trait if you have a functioning allele and a different trait if you don't have a functioning allele. If you choose eye color, and Brown (B) is dominant to blue (b), start by just writing the phenotype (physical characteristic) of each one of your family members. So hopefully, you've enjoyed that. These particular combinations are genotypes. You're not going to have these assort independently. Well, there are no combinations that result in that, so there's a 0% probability of having two blue-eyed children. Shouldn't the flower be either red or white? And let's say we have another trait. I'll use blood types as an example. Well, in order to have blue eyes, you have to be homozygous recessive. It could be useful for a whole set of different types of crosses between two reproducing organisms. And we can do these Punnett squares. You could get the B from your mom, that's this one, or the O from your dad. They both express themselves.

Sometimes grapes are in them, and you have a bunch of strawberries in them like that. And I'm going to show you what I talk about when we do the Punnett squares. This results in pink. I met a person, who's parents both had brown eyes, but ther son had dark brown? So these are both A blood, so there's a 50% chance, because two of the four combinations show us an A blood type. And clearly in this case, your phenotype, you will have an A blood type in this situation. So an individual can have-- for example, I might be heterozygous brown eyes, so my genotype might be heterozygous for brown eyes and then homozygous dominant for teeth. And I looked up what Punnett means, and it turns out, and this might be the biggest takeaway from this video, that when you go to the farmers' market or you go to the produce and you see those little baskets, you see those little baskets that often you'll see maybe strawberries or blueberries sitting in, they have this little grid here, right there. If you have two A alleles, you'll definitely have an A blood type, but you also have an A blood type phenotype if you have an A and then an O. And if I were to say blue eyes, blue and big teeth, what are the combinations there? In terms of calculating probabilities, you just need to have an understanding of that (refer above).

Hopefully, you're not getting too tired here. The other plant has a red allele and also has a white allele. It doesn't even have to be a situation where one thing is dominating another. We care about the specific alleles that that child inherits. You could use it to explore incomplete dominance when there's blending, where red and white made pink genes, or you can even use it when there's codominance and when you have multiple alleles, where it's not just two different versions of the genes, there's actually three different versions. If you have them together, then your blood type is AB.

Are blonde hair genes dominant or recessive? Well the woman has 100% chance of donating "b" --> blue. Let's say their phenotype is an A blood type-- I hope I'm not confusing you-- but their genotype is that they have one allele that's an A and their other allele that's an O. Mother (Bb) X Father (BB). What's the probability of a blue-eyed child with little teeth? Maybe there's something weird. So if I'm talking about the mom, what are the different combinations of genes that the mom can contribute? So big teeth, brown-eyed kids. Let's see, this is brown eyes and big teeth, brown eyes and big teeth, and let me see, is that all of them? So this might be my genotype. Very rare but possible.

Now, if they were on the same chromosomee-- let's say the situation where they are on the same chromosome. Now if we assume that the genes that code for teeth or eye color are on different chromosomes, and this is a key assumption, we can say that they assort independently. Recommended textbook solutions. It's kind of a mixture of the two. So let me pick another trait: hair color. So the child could inherit both of these red alleles.
