Question

When dark-colored fur gives mice a 1% competitive advantage and 1% of the population begins with dark fur, in about 1,000 years, 95% of the population will have dark fur. Which of the following statements is true?
A. Dark-colored rock pocket mice, in this population, have fewer offspring than light-colored rock pocket mice.
B. If dark-colored rock pocket mice had a competitive advantage of 0.1%, it would take more than 1,000 years for 95% of the population to have dark fur.
C. If dark-colored mice had a competitive advantage of 5%, it would take more than 1,000 years for 95% of the population to have black fur.
D. If dark-colored mice had a competitive advantage of 10%, it would take more than 1,000 years for 95% of the population to have black fur

Answer 1

Answer:

"If dark-colored rock pocket mice had a competitive advantage of 0.1%, it would take longer for 95% of the population to have dark fur." the statement is true

Explanation:

The greater effect of the crossing over is basically to spread the variation through the population. This is the basic difference even between sexual and non sexual mode of reproduction.The offspring produced might get get more variety when compared to the parent.  From this the genetic recombination happens. This also often lead to the intrachromosomal mixing that takes place between the alleles and the homologous pair. This is the exchange of the chromosome segments among the non sister chromatids in meiosis.
