The offspring of two koalas develops a genetic disease. when scientists studied the parents’ dna, they found that both parents carried harmful recessive genes passed down from the exact same lineage. which process contributed to the offspring’s genetic disorder? a. biomagnification b. eutrophication c. inbreeding d. predation

C. Inbreeding

Explanation:

It says that the parents' recessive gene came from the exact same lineage, meaning they are related. The continued inbreeding made the recessive gene more popular.

C. inbreeding

Explanation:

Inbreeding is mating between the individuals which are closely related. Because of inbreeding, heterozygosity is reduced while homozygosity is increased in a population. Because of inbreeding a deleterious or recessive trait becomes more popular in a population. This condition is also known as inbreeding depression. Since the two individuals are closely related so their lineage also remains the same.
