Correct Answer: D
Solution :
Test cross is determines whether an individual is homozygous or heterozygous for dominant character. The offspring of \[{{F}_{1}}\] is crossed with recessive parent. The ratio will be 1 : 1 in case of hybrid or heterozygous individual. In case of double heterozygote (\[\text{eg,}\,\,\text{RrYy}\]), crossed with recessive (\[\text{rryy}\]) the ratio will be 1:1:1:1. Test cross helps to find out genotype of parents.You need to login to perform this action.
