professor190 [17]

Answer:

The situation in which some individuals have greater reproductive success than other individuals in a population. Along with variation and heritability, it is one of the three conditions necessary for evolution by natural selection.

There are so many factors that contributed to this over time, reproductive success differs and it could be attributed to hereditary and variation as well. Most often, the hereditary plays the most role out of all as the viability of both eggs and sperms could have been inherited from parents or being affected as a result of environmental factor or nutrition or other factors.

For instance, if one has a rhesus factor of negative and went ahead to marry another male counterpart with negative rhesus factor, this sedomly leads to miscarriage which could have been controlled had it been they were thoroughly counseled. Furthermore, physical factor such as accident could damage one spermatical vessicles that houses the sperm cells which render such an individual to be unable to donate a viable sperm cell for reproduction.

Those with high rate of reproductive success thrives as result of having many offspring which increases their chances of having more offspring than those with little success rate.

horsena [70]

Complete question:

A sample of butterflies contained 50% yellow-winged individuals and 50% black-winged individuals. In this species, wing color is determined by a single gene with two alleles, and the allele for black is dominant. Which of the following statements about the allele frequencies in the sample would most likely be true?  Do not assume that this sample was obtained from a population in genetic equilibrium.

a)The frequency of the yellow allele is greater than that of the black allele.

b)The allele frequency of yellow is 3 times the allele frequency of black.

c)The allele frequency of yellow is twice the allele frequency of black.

d)The allele frequencies of black and yellow are equal.

e) The allele frequency of black is greater than the allele frequency of yellow.

2.Now assume that the population of butterflies sampled in question above is in Hardy-Weinberg equilibrium. Also assume that the sample is random and large enough that the allele frequencies in the sample equal the allele frequencies in the population.  What is the frequency of the allele for a) yellow wings in the population? Assuming Hardy-Weinberg equilibrium in question 1, what would the correct answer be and why?

Answer:

  • a)The frequency of the yellow allele is greater than that of the black allele.
  • f(b) = q = 0.71

How can flowers help other organisms? What type of relationship is it?
mr Goodwill [35]

Well, flowers give insects like bees and butterflies nectar. That's their food. In return, the insects spread the flower's pollen so that other plants like its type can be fertilized.

This is mutualism - a symbiotic relationship were two organisms benefit.

Happy to help!
