A population of black cats has been interbreeding. However, in one litter, a sole gray kitten is born. The successive generations now have a few gray cats. Which mechanism is responsible for introducing this new allele in the cat population?
A. Gene selection
B. Gene mutation
C. Gene flow
D. Genetic drift
Answer (2)
the answer is b. gene mutation
The introduction of gray cats in the population is due to a gene mutation, which creates new alleles that can spread through successive generations. This process occurs independently of gene flow, genetic drift, or natural selection. Therefore, the correct answer is B. Gene mutation.
