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
What does positive assortive mating mean?
a. Individuals that are different for a certain trait are more likely to mate
b. Individuals that are alike for a certain trait are less likely to mate
c. Individuals that are alike for a certain trait are more likely to mate
d. Any individuals may mate randomly
Give typing answer with explanation and conclusion
In 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?
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?
