How the positive and negative DNA markers are used in genetic engineering?
In cats yellow is due to gene B and black to its allele b. These genes are located on the X chromosome (sex-linked). The heterozygous results in calico (tortoise shell). What kinds of offspring (sex & color) are expected from the cross: black male & calico female? Most calico males are sterile, why?

The weight of the fruit of one variety of squashes is determined by three pairs of genes: AABBCC produces 6 lb squashes and aabbcc produces 3 lb squashes. Each dominant allele adds 1/2 lb tothe base weight (3 lb). If a pure breeding line that produced 6 lb squashes was crossed with a pure breeding line that produced 3 lb squashes, what would be the phenotypic ratio of the F1 and the F2?
