honeybees ants and certain Honeybees ants and certain other

Honeybees, ants, and certain other insects are haplodiploids. In such species, females arise ___/8 from fertilized eggs and are diploid, while males arise from unfertilized eggs and are haploid. In bees, longs wings are dominant over short wings, and black eyes are dominant over white eyes. These two traits assort independently. A drone (male) with short wings and black eyes is crossed a queen that is heterozygous for both genes. a) What are the predicted phenotype frequencies of males and females (separately)? b) What phenotype frequencies would you expect if 80% of the eggs laid become female (combine males and females this time)?

Solution

The genotype of male drones is wB. The genotype of female queen is WwBb

Males:

1 Normal wings and black eyes.

1 normal wings and white eyes

1 short wings black eyes

1 short wing white eyes

Females:

2 normal wings black eyes

2 short wings black eyes
