An individual has a genotype containing four pairs of genes denoted AA, Bb, Dd and ee; genes are located on autosomes. What is the genotype and ratio of this individual to produce gametes in the following cases: a) Four pairs of genes AA, Bb, Dd, ee are located on four different homologous chromosome pairs?
b) Two pairs of genes AA and Bb are located on a homologous chromosome pair; two pairs of genes Dd and ee are located on the same pair of homologous chromosomes?
c) The three pairs of genes AA, Bb, and Dd (in order) are located on one homologous chromosome pair, and the ee gene pair is located on another homologous chromosome pair?
It is known that the structure and number of chromosomes do not change during meiosis.
