Of the following, which is the least plausible hypothesis for why natural selection has not eliminated genes for male homosexuality? a. Perhaps the relatives of a homosexual male have more than an average number of children. b. Homosexual people might spread their genes by helping their brothers and sisters rear their children. c. Maybe there is no gene for homosexuality. Instead, an environmental event produces an epigenetic effect that can be transmitted from one generation to the next. d. Some homosexual men have children.
Sexual reproduction provides an advantage to organisms because it increases the
Β
A.
size of the genome of a species.
Β
B.
genetic variability in a population.
Β
C.
fitness of individual alleles of a gene.
Β
D.
number of mutations during cell division.
Which of the following statements is an evolutionary advantage of sex and sexual reproduction?
Β
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.

- Under a simple model, the evolution of asexual reproduction strategies will take over a population. The model relies on two assumptions. Which of the following are the assumptions? Β a. Reproductive mode does not affect how many offspring are produced by a female. Β b. Reproductive mode does not affect the sexual selection on males Β c. Reproductive mode does not affect the probability of offspring survival Β d. Both a. and b.Β Β e.

Fur colouration is the result of a new adaptive behaviour where pocket mice rolled in lava dust to camouflage themselves. b. It is the result of the same, single mutation in all populations. C. Different mutations cause similar dark colouration in different populations. d. One specific mutation causes black or white fur depending on the population. e. Fur colouration is the result of dietary changes in different environments, not natural selection.arrow_forwardDarwin's concept of evolution "the theory of decent with modification through variation and natural selection" can best be demonstrated by which of the following examples? Β a. A giraffe stretches his neck to reach higher branches. The exercise of stretching up strengthens the muscles in the giraffe's neck and legs. This ability to stretch is also seen in the giraffe's offspring. Β b. A monkey accidentally drops her fruit in the salty water of a bay. She recovers the fruit and eats it. She discovers the fruit is cleaner and tastes better after it has been in the salty water. She continues to wash the fruit in the bay before eating it. Her offspring see what she has done and also wash their fruit in the salty water. Soon, the whole population of monkeys is washing their fruit. Β c. Several turtles hatch from a clutch of eggs buried in the sand on a beach. One of the turtles is the color of the sand; the others are darker in color.

- Consider all of the species on earth.Β Some scientists believe that the genes for growth and reproduction have been under evolutionary forces for longer than those involved in maintenance and repair.Β Which statement below best supports their theory? a. Most species die after producing offspring. b. βSurvival of the fittestβ is true. c. Most animal species mate for life. d. Only the more intelligent organisms live long lives.arrow_forwardBackground: In class we did a project about m and mβs and there ability to evolve and natural selection. (Yes I know they canβt actually evolve it was just used as a example in class) however I canβt figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blankarrow_forwardWith regard to biological evolution, which of the following statements is incorrect? Explain why.A. During its lifetime, an animal evolves to become better adaptedto its environment.B. The process of biological evolution has produced species thatare better adapted to their environments.C. When an animal is better adapted to its environment, the process of natural selection makes it more likely that the animalwill reproduce.arrow_forward
