Dihybrid sex linked punnett squares in Salinas

In this case there is only one trait Next lesson. And I did it lowercase h because it is a recessive trait. Well, the daughters are going to be the XX scenarios. And so that one X chromosome is going to have the hemophilia allele. There are more than two-choices for the allele.

So, these are the two scenarios in which they have a daughter. Monohybrid Dominant and Recessive. An organism with a recessive allele for a particular form of a trait will have that form only when the dominant allele for the trait is not present. The phenotypic ratio would therefore be 1 : 2 : 1.

Tall is dominant over short, and Black is dominant over white.

The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. So these are all the different combinations that she could contribute. Let's do a bunch of these, just to make you familiar with the idea.

Well, which of these are homozygous dominant? So if you look at this, and you say, hey, what's the probability-- there's only one of that-- what's the probability of having a big teeth, brown-eyed child? Surface currents, the Ekman spiral, and Ekman transport.

The phenotypic ratio would be 1 : 1 : 1 : 1. Usually found on the X chromosome. In this case you were told the parents were heterozygous. But now let's cross these two with a Punnett square. X-linked alleles are always expressed in males because males have only one X chromosome.

If you said, given that they had a son, what is the percent chance that they don't have hemophilia?
