What is the probability that each of the following pairs of parents will produce the given offspring: 1. AABbCc x aabbcc à AaBbC
ICE Princess25 [194]

Answer:

1) AaBbCc, 50% - 2) AAbbCC, 3,125% - 3) AaBbCc is 12,5%.

Explanation:

<u>1º cross</u>.

                          32/64  AabbCc (shown as the symbol "---" in the      

                          punnet square)

The probability of producing offspring with genotype AaBbCc is 50%.

F1 Genotype)  2/64 AAbbCC

                       The rest of the progeny have different genotypes that are represented with the symbol "---" in the punnet square.

The probability of producing offspring with genotype AAbbCC is 3,125%.

"a man with genotype bb and a woman wth genotype BB have four children. how many of the children are likely to have blue eyes"
Sonja [21]

Answer:

No children will have blue eyes all of them carry brown eyes only.

Explanation:

The cross between a male with bb genotype and female with BB genotype will be as follows :

The gametes will be formed

male: b and b

female: B and B

By Punnett square:

        B          B

b       Bb        Bb

b       Bb        Bb

As all the offspring will have a heterozygous condition with dominant B (Brown) and recessive b( blue) so there are no offspring will be with the phenotype of the blue eyes.
