Chapter 10, Problem 3AC
Summary Introduction
To review:
The consequences of assortative mating amongst humans in a society. Also, justify whether a society that mated randomly would be advantageous or not.
Introduction:
With time, the Americans have incorporated genes within their gene pool of the people from various cultures and societies. The various immigrants have brought their culture from their respective countries, which now is difficult to segregate due to perfect blending. Such a society is known as ‘melting pot’.

Students have asked these similar questions
Name some traits for which you think humans exhibit nonrandom mating. Is mating for these traits likely to be positive or negative assortative mating? Name some traits for which you think people mate randomly. How could you test whether mating for these traits is random?
The frequency of an autosomal recessive condition is 0.001 (1 in 1000) in a population.
Assuming individuals mate at random, what is the chance that two heterozygous individuals will mate?
Express your answers using three significant figures.
Intrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.

- The good genes model of sexual selection is a popular hypothesis for mate choice. What is an underlying flaw with the hypothesis that must be explained?arrow_forwardIn some animal species, being tall is dominant over being short. If a homozygous dominant individual mates with a short individual, what is the chance that their offspring will be heterozygous?arrow_forwardAssume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.arrow_forward
- What is purposeful control over mating by choice of parents for the next generation?arrow_forwardHumans are basically choosy. When it comes to choice of mate, which type is more advantageous to the future of a gene pool, choosing one who is your complete opposite or choosing someone who is so like you? Defend your answer.arrow_forward|(A) A well trained alien biologist visiting earth would be able to tell that the mating system of gorillas is strongly polygynous and that of man's weakly polygynous. How could he/she/it tell this just by looking at gorillas and humans? (B) Is harem polygyny an ESS or have "cheater" behaviors evolved to exploit or exist within these systems? (C) If your answer was yes then describe a cheater behavior within a polygynous system.arrow_forward

The allele for the color of the tail is sex linked and the red allele is found on the W chromosome and the blue allele is found on the Z chromosome. You mate a male and female and they have 3 female offspring. What is the phenotypic ratio for tail color for their offspring?

Which of the following options below inaccurately matches our shared characteristics with each type? Select one: a. moderate to high degree of sexual dimorphisms - tournament b. moderate to highly monogamy in coupled relationships - tournament c. male mate pickiness - pair bonding d. high parental investment - pair bonding e. females selecting mates for parenting skill - pair bonding f. moderate to high variability in male reproductive success & aggression - tournamentarrow_forward
- Lions and tigers are separate species. However, on rare occasions (especially in zoos) they have been known to mate and produce hybrid offspring (ligers & tigons!). Explain, with reference to the mechanisms of reproductive isolation, why they are separate species even though they can mate. (1-2 sentences) **Please answer in simple, easily understandable terms**arrow_forward(I've asked this question twice, but still haven't gotten a clear answer. I'm still confused on this.) Lions and tigers are separate species. However, on rare occasions (especially in zoos) they have been known to mate and produce hybrid offspring (ligers & tigons!). Explain, with reference to the mechanisms of reproductive isolation, why they are separate species even though they can mate. (1-2 sentences) **Please answer in simple, easily understandable terms**arrow_forwardRama the cama, a llama-camel hybrid, was born in 1998. The idea was to breed an animal that has the camel's strength and endurance, and the llama's gentle disposition. However, instead of being large, strong, and sweet, Rama is smaller than expected and has a camel's short temper. The breeders plan to mate him with Kamilah, a female cama. What potential problems with this mating should the breeders anticipate?arrow_forward
