Q1. In babbits there are two dissimilar independently segregating autosomal loci that affect coat colour. The protein product of gene A converts a colourless precrsor (V) to a second colourless compound(W).compound W is converted to a tan pigment by the protein product of gene B. babbits that do not produce tan are white.

Consider a cross between two babbits that are both heterozygous at A and B loci (A/a B/b).what will be the phenotypes and genotypic ratio of their progeny? Give details.

Q2. The cell walls of bacteria, fungi, and plant cells and the extracellular matrix of animal cells are all external to the plasma membrane. Which of the following is a characteristic of all of these extracellular structures?
