Question

2. Human growth is controlled by several pairs of unlinked genes. If we neglect environmental factors and conditionally limit ourselves to only three pairs of genes, then we can assume that in some population the shortest people have all recessive genes and height 150 cm, the tallest - all dominant genes and height 180 cm.

Tasks:

1. Determine the genotypes of the family and their children, with a wife's height of 155 cm, with a husband's height of 175 cm

2. What kind of gene interactions does this inheritance refer to? Describe!

3. Give 3 examples of this type of gene interaction

Answer 1

1.Father - AA

Mother - Aa

Offsprings - AA, Aa, aA, aa

2.Epistatic gene interaction

3.Combs in Chickens

Flower colour in peas

Coat color in horses
