Probability of genotype
What is the probability that cross between genotype AaBbCcDd and AaBbCcDd will produce AaBbCcDd?
For these type of questions, remember one thing that the probability of a heterozygote (Aa) is 2/4 or 1/2 and probability of a homozygote AA or aa is 1/4
Calculations to find probability of genotype
Now, start calculations…
aabbccdd = 1/4 * 1/4* 1/4* 1/4 = 1/256
AaBbCcDd = 1/2* 1/2* 1/2* 1/2 = 1/16
AABBCCDD = 1/4 * 1/4* 1/4* 1/4 = 1/256
AaBBccDd = 1/2* 1/4* 1/4* 1/2 = 1/64
AaBBCCdd = 1/2* 1/4* 1/4* 1/4 = 1/128
