Question

i need some help with punnett squares

Answer 1

ask away

Answer 2

Okay, what questions do you have?

Answer 3

so how do i create a cross by what the question is?
like when the question is " the offspring of a crooss between 2 white-tail deer resulted in 2 albino deer" what would the cross for that be?

Answer 4

The kind of cross you set up depends on how many different genes are responsible for transmission, how many alleles (kinds) of each gene there are, and the specific pattern of expression (like the typical dominant/recessive, codominant, incompletely dominant, etc.)

Those are the things to look for when you read the problem and set up the solution.

Answer 5

Clear?

Answer 6

um can you give me an example?

Answer 7

Okay. To use your deer problem, let's assume that coat color is controlled by one gene with two alleles. If the deer has at least one dominant allele, A, it will have coat color. If it does not have a dominant allele "A" then it will be albino.''

Let's further assume that both the baby deer's parents are heterozygous for coat color - that is, they have one "A" allele which is enough to give them color and one "a" allele. When they mate, the cross looks like this:



Hopefully, the drawing inserted itself there... I'll post it then explain it
