You find two closely related species of fly, one (P) of which appears to reproduceparthenogenetically (a form of asexual reproduction) while the other (S) reproduces sexually.In the same location, I find a third kind of insect, a sterile defensive form with enlargedmandibles. Because it is sterile, I conclude this form must be produced by either P or S. Whichdo you think is most likely the producer of the sterile defensive individuals?Answer:

Closely related species are the group of species that they have very few boundaries. The…

Plants and animals are both capable of reproducing asexually. In which typesof asexual reproduction are common to both organisms?
If an organism reproduces very freely by asexual means, is there any advantage to its also reproducing sexually?
(a) Distinguish between asexual and sexual reproduction. Why isvegetativereproduction also considered as a type of asexual reproduction?(b) Which is better mode of reproduction : Sexual or Asexual? Why?
One reason that worker bees forgo their own reproduction to help their sister (the queen) reproduce is that female bees are more closely related to their sisters than they are to their own offspring. This quirk of genetics results from the fact that bees have haplodiploid sex determination, in which females are diploid, with a mother and a father, but males are haploid, developing from unfertilized eggs. Because males are haploid, they produce sperm by mitosis. Explainwhy haplodiploid sex determination causes females to be more closely related to their sisters than to their offspring.
Explain how and why the Queen bee abort the sexual maturation of the worker bees?
Sexual reproduction in unpredictable environments provide immediate benefits to individuals including the following except -- A. There are more opportunites for offspring to specialize in different niches in an environment. B. The chance that the offspring of sexual ndividuals will be well-matched to their environment increases. C. Bet-hedging strategies are involved for increasing offspring fitness. D. Reduction of competition for resources among genetically related offspring.
Some organisms—for example, certain fungi—reproduce asexually when the environment is favorable and sexually when the environment becomesunfavorable. What might be the evolutionary advantage of sexual reproduction with the associated process of meiosis during unfavorable conditions?
The ameba, a single called organism, reproduces asexually. Variation in an ameba would most commonly occur through
Why is sperm usage biased when femalefruit flies mate twice?
The hymenopterans have a method of sex determination called ____, which is a type of meiotic parthenogenesis in which a fertilized egg develops into a female and an unfertilized egg develops into a male. This system is based on a single gene called the ____ gene (you may abbreviate the name of the gene). If an individual is heterozygous for this gene, it results in the production of female-specific mRNA from the second gene called the ____ gene, which in turn results in female-specific mRNA from a third gene called the ____ gene, resulting in a genetic cascade that causes the development of a female (you may abbreviate the gene names)
Which of the following is an advantage of asexual reproduction over sexual reproduction?
