The peas were observed to be self-pollinating, assuring to a high confidence that any given seed would be homozygous. She collected seed from plants that had purple flowers from two locations, one in the tundra of the Rocky Mountains and the other in the coastal forest of Georgia. She made crosses between them, and the F 1 hybrid, grown hydroponically along with the parents, also was white. Describe an epistatic interaction that would produce this color of flowers in the F 2 . Give a diagramatic pathway with the postulated genotypes indicated to be coding hypothetical enzymes in biochemical steps for purple color.
Sex determination has a variety of genetic organizations.
A form of genetic linked disorder in humans happens to prevent the development of maleness, even though the chromosomes have normal 22 pairs of autosomes and an XY sex chromosome constitution. It is called testicular feminization syndrome. Explain it's inheritance.
