Question

Example of gene interaction involving single gene loci is

Answer 1

Explanation:

location of many genes (Mendel's factors) was determined by Thomas Hunt Morgan and his coworkers in the early 1900's. Morgan's experimental organism was the fruit fly (Drosophila melanogaster). Fruit flies are ideal organisms for genetics, having a small size, ease of care, susceptibility to mutations, and short (7-9 day) generation time. The role of chromosomes in determination of sex was deduced by Morgan from work on fruit flies.

Answer 2

Answer:

Production of the petal pigment malvidin is controlled by one gene, but its synthesis can be suppressed by another gene at a different locus. Later researchers discovered that flower petal color can also be controlled by dominant epistatic forces.
