Chapter 19: Q. 16 (page 484)

Solve for the genetic structure of a population with 12homozygous recessive individuals (yy), 8homozygous dominant individuals (YY), and 4 heterozygous individuals (Yy).

Short Answer

Expert verified

Frequency of homozygous recessive individual =1224=0.50

Frequency of homozygous dominant individual = 824=0.33

Frequency of heterozygous dominant individual = 424=0.17

Step by step solution

01

Hardy- Weinberg principle : 

The Hardy- Weinberg equilibrium, model, theory, or rule is also known as the Hardy- Weinberg principle. In the absence of evolutionary effects, the frequencies of alleles and genotypes in a population will, on average, remain constant from generation to generation.

02

 Explanation : 

Hardy-Weinberg equation :

p2+2pq+q2=1

where,

p2is frequency for homozygous genotype YY.

q2is frequency for homozygous genotype yy.

2pqis frequency for heterozygous genotype Yy.

Total number of individuals = 24

Frequency of homozygous recessive individual = 1224=0.50

Frequency of homozygous dominant individual = 824=0.33

Frequency of heterozygous dominant individual =424=0.17

Which of the following evolutionary forces can introduce new genetic variation into a population? a. natural selection and genetic drift

b. mutation and gene flow

c. natural selection and nonrandom mating

d. mutation and genetic drift

Figure19.8 In recent years, factories have become cleaner, and less soot is released into the environment. What impact do you think this has had on the distribution of moth color in the population?

One of the original Amish colonies rose from a ship of colonists that came from Europe. The ship鈥檚 captain, who had polydactyly, a rare dominant trait, was one of the original colonists. Today, we see a much higher frequency of polydactyly in the Amish population. This is an example of:

a. natural selection

b. genetic drift

c. founder effect

d. b and c

What is the difference between micro- and macroevolution?

a. Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants.

b. Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms.

c. Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time.

d. Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.

Describe natural selection and give an example of natural selection at work in a population.
