Answer:
Explanation:
Let the allele for dark color be represented by "D" and the allele for light color be represented by "d"
Also D is dominant over d
Similarly, let the allele for obese trait in mice be represented by "O" and the allele for lean trait in mice be represented by "L"
Obese and lean exhibit incomplete dominance
Genotype of true breeding dark and obese mice be DDOO
Genotype of true-breeding lean and light mice is ddLL
Offspring from F1 cross -
DdOL
F2 cross is between DdOL * DdOL
DO DL dO dL
DO DDOO DDOL DdOO DdOL
DL DDOL DDLL DdOL DdLL
dO DdOO DdOL ddOO ddOL
dL DdOL DdLL ddOL ddLL
dark and intermediate between obese and lean offspring genotype –
2 DDOL, 4 DdOL
So total six out of sixteen offspring are dark and intermediate between obese and lean -
