Question

Calculate the probability of obtaining a zygote with genotype aabbccdd if a cross is made between individuals whose genotypes are aabbccdd and aabbccdd respectively

Answer 1

1/2

Explanation:

Given that,

Genotype = AaBBccDD

Cross of individuals having genotypes = aaBBccDD & AAbbCCDD

so,

    a      a

A   Aa   Aa

A   Aa   Aa

∵ Aa = 1

      b      b

B    Bb    Bb

b    bb    bb

∵ bb = 2/4 = 1/2

    c      c

C   Cc   Cc

C   Cc   Cc

∵ Cc = 1

    D      D

D   DD   DD

D   DD   DD

∵ DD = 1

Thus, the probability of AaBBccDD

= 1 * 1/2 * 1 * 1

= 1/2
