homozygous recessive is crossed with a heterozygote, what percent chance is there of getting a heterozygous genotype in f1?

Solutions

Expert Solution

We can use the following Punnett square to do the crossing and get the results. Let aa is the recessive homozygote and Aa is heterozygote.

                               l    a   l   a   l

                             A l Aa l Aa l

                             a l aa l aa l

Now, we see that of the above four offsprings of generation F1, two are heterozygous. Therefore, percent chance of getting a heterozygote in this cross is 50%.

Thanks!

What is the difference between heterozygous and homozygous individuals?
Part A What is the difference between heterozygous and homozygous individuals? Homozygotes have one chromosome while heterozygotes have two similar chromosomes. The homozygote will express the dominant trait and the heterozygote will express the recessive trait. All of the gametes from a homozygote carry the same version of the gene while those of a heterozygote will differ. Heterozygotes carry two copies of a gene while homozygotes only carry one. Part B When constructing a Punnett square, the symbols on the...
