Answer:
Skin pigmentation in humans
Explanation:
Skin pigmentation is a very common example in polygenic inheritance. This inheritance is represented by two gene pairs: Aa and Bb.
Thus, A and B determine the production of the same amount of melanin pigment and have additive effect. Therefore, there are several shades of color in human skin, according to the amount of genes A and B.
Offspring of parents with one very dark skinned and one very light skinned may give an intermediate skin color. Heterozygous parents for skin color can lead to offspring with darker or lighter skin than their own.
Answer:
Cross the flies with the flies from another population
Explanation:
Inbreeding is the mating between the closely related individuals of a population. Inbreeding reduces the viability of the progeny over a generation since it increases homozygosity. When the flies of a small population interbred over generations, the increased homozygosity reduces the viability of the flies. To counteract it, one should mate these flies with the flies from another population. This would increase heterozygosity and thereby would increase the survival and fitness of the progeny.
