Which of the following statements is an evolutionary advantage of sex and sexual reproduction?
A. Sex and recombination results in decreased genetic variation in a population and maintains advantageous traits.
B. Sex and recombination can bring beneficial alleles together when producing offspring.
C. Sex and recombination results in the inheritance of all the genetic information available from both parents.
D. Reproduction is less risky when gametes from two individuals must fuse.
In many zoos, artificial insemination of female tigers is becoming common practice. Semen is collected from male tigers in various zoos around the world.frozen in liquid nitrogen, and shipped to zoos where it is used to inseminate female tigers in estrus
a) Why do you think this is being done and how will it affect the population?
b) Do you think these effeorts are enough to prevent a genetic bottleneck from occuring?
c) what conditions do you think are nessesary to ensure the genetic diversity of zoo populations?

The original parents are not the same species because they produce hybrids that impair the species’ development or survival in its environment. D. The original parents are not the same species because they produce hybrids that can have reduced viability and fertility when they mate.arrow_forwardWhich observation led Thomas Morgan to realize that the gene for fruit fly eye color was located on a sex chromosome? a.
