This is a diagram of a family tree. Males are shown as squares. Females are shown as circles. Alleles are shown as the small circles with each allele given as black, striped, grey or white. The diagram is an example of identity by descent. Why? a. Because the final individual has inherited two identical alleles from the same ancestor b. Because the final individual has the same alleles as three generations previous C. Because the final individual is homozygous for the black allele d. Because there are homozygous individuals throughout the pedigree e Because the entire tree stems from a single couple Clear my choice

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
