Question
5.Test cross has phenotype ratio of(1 Point)1:1:11:1:1:11:2
Solution
It seems like there's a mistake in your question as the ratios provided are not clear. However, in a test cross, the typical phenotypic ratio is 1:1. This is because a test cross is performed to determine the genotype of an individual with a dominant phenotype. This individual is crossed with a homozygous recessive individual. If the individual in question is homozygous dominant, all offspring will display the dominant phenotype. If the individual is heterozygous, approximately half of the offspring will display the dominant phenotype and half will display the recessive phenotype, hence the 1:1 ratio.
