Analysis of allelic diversity in maize demonstrated that by 4400 years ago, maize had lost much of its genetic diversity. This loss of diversity can be explained by
A) a genetic bottleneck.
B) strong artificial selection.
C) genetic drift.
D) a and b
E) a, b, and c
Genetic Diversity
The total number of genetic characteristics in the genetic makeup of a species, facilitating adaptability and survival.
Genetic Bottleneck
A sharp reduction in the size of a population leading to a decrease in genetic diversity and potential changes in the population structure.
Artificial Selection
The selective breeding of animals and plants to encourage the occurrence of desirable traits. Individuals with preferred characteristics are mated or cross-pollinated with other individuals having similar traits.
