If race is not a biological concept, is it still useful to study race?
A.
No, it's not useful.
B.
Yes, because race is a social concept and racism can cause inequalities that affect people's lives and health.
C.
Yes, because race actually is a biological concept that is supported by science.
D.
Yes, because race is a social concept but racism doesn't affect people's lives.

- There is a population of cats and 16% of the cats this population show a recessive trait. a. What is the frequency of the recessive allele? b. What is the frequency of the dominant genotype? c. What is the frequency of cats with the heterozygous genotype?arrow_forwardAllele frequency refers to the fraction of individuals with a particular version of a given gene.What effect does natural selection have on the allele frequency of a population? A. It causes the allele frequency to resemble that of a small number of individuals that became separated from the rest of the population. B. It causes random changes and the allele frequency of certain traits may increase or decrease. C. It increases the frequency of alleles that improve a species' survival in a particular environment. D. It greatly reduces the total population, which increases the effects of genetic drift on allele frequency.arrow_forwardWhat is a adaptive traitarrow_forward
