A) Genes A and B are linked
B) Independent segregation of genes A and B
C) Mendelian dihybrid inheritance
D) Polygenic inheritance
Correct Answer: A
Solution :
In this type of parents have the genotypes AAbb and aaBB, when they are crossed the offsprings with the genotype AaBb produced. This offspring is crossed with the individual having the genotype aabb. If the genes A and B show independent assortment, then the four types of offspring will be produced in the ratio 1 : 1 : 1 : 1. But this does not happen, hence the genes A and B are linked.You need to login to perform this action.
