Q1. Atherosclerosis is a progressive disease of blood vessels that is responsible for millions of deaths each year. Express the disease process, noting the involvement of specific cell/tissue types and molecules.

Q2. True breeding tall red flowered plants crossed with dwarf white flowered plants. The resulting f1 generation consists of all tall pink flowered plants. Assume that height and flower colour is each determined by a single gene locus on different chromosomes; predict the results of an f1 cross of dihybrid plants. Select appropriate symbols for the allele’s height and flower colour genes. List the phentypes and predicted ratios for the f2 generation.
