Answer:
Genotype
GGCuCu : GGCucu: GgCuCu: GgCucu : GGcucu: Ggcucu: ggCuCu: ggCucu: ggcucu
1 : 2: 4: 4: 2: 2: 2: 1
Phenotypic ration
Black & curled ears : Black & normal ears: Gray & curled ears : Grey & normal years
11: 4: 4: 1
Explanation:
Given -
Curled ears allele, Cu is dominant over an allele for normal ears , cu.
Also Black color (G) is dominant over allele for gray color (g)
Genotype of parent
gray cat homozygous for curled ears - ggCuCu
homozygous black cat with normal ears- GGcucu
offsprings produced were having genotype - GgCucu
Now cross is carried out between F1 progeny and these are as follows -
GgCucu * GgCucu
