Question

Which of the following statements is/are true?
A. Redheaded females in a population will only breed with red-headed males. The yellow-headed females will only breed with yellow-headed males. This population lives in the same geographic area. The red and yellow individuals could breed and produce fertile offspring, but they normally do not. This would be an example of sympatric speciation.
B. Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population.
C. Redheaded females in a population will only breed with red-headed males. The yellow-headed females will only breed with yellow-headed males. The red and yellow populations live on separate continents and rarely met in nature. The red and yellow individuals could breed and produce fertile offspring, but they normally do not. This would be an example of sympatric speciation.
D. Sympatric speciation is never due to sexual (mate) selection.
E. Sympatric speciation requires geographic isolation.

Answer 1

Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population.

Explanation:

Sympatric speciation is an event/situation whereby organisms of the same species:

- live in the same territory or nearby territories ( i.e do not live in geographical isolation)

- DO NOT interbreed, but select a sexual mate from a much diverse territory to yiels new species or offsprings that are genetically different from their parents, and causing uneven gene flow or disruption of alleles known to have been prevalent among the parent organisms

So, only option B is true
