HEYYOU Group Title

1. Natural selection acts directly on (1 point)alleles. genes. phenotypes. mutations. 2. In a fox population, the allele frequency of a gene for red fur changes from 20 percent to 30 percent. What can you say about that population of foxes? (1 point)The population is expanding. The population is evolving. The population is decreasing. The population is not evolving. 3. Sexual reproduction among members of a population results in (1 point)different types of alleles in the gene pool. changes in the allele frequences in the gene pool. no changes in the allele frequences in

The number of phenotypes produced for a given trait depends on (1 point)the number of genes that control the trait. which form of the trait is dominant. the allele frequencies of the various alleles. the relationship of allele frequencies to Mendelian ratios. 5. A polygenic trait can have (1 point)many possible genotypes, but few possible phenotypes. many possible genotypes, producing many posible phenotypes. fewer phenotypes than most single-gene traits. fewer genotypes than most single-gene traits.

    1. Natural selection acts directly on (1 point) (0 pts) alleles. (0 pts) genes. (1 pt) phenotypes. (0 pts) mutations. 1 /1 point 2. In a fox population, the allele frequency of a gene for red fur changes from 20 percent to 30 percent. What can you say about that population of foxes? (1 point) (0 pts) The population is expanding. (1 pt) The population is evolving. (0 pts) The population is decreasing. (0 pts) The population is not evolving. 1 /1 point 3. Sexual reproduction among members of a population results in (1 point) (0 pts) different types of alleles in the gene pool. (0 pts) changes in the allele frequences in the gene pool. (1 pt) no changes in the allele frequences in the gene pool. (0 pts) an absence of genetic variation in the population. 1 /1 point 4. The number of phenotypes produced for a given trait depends on (1 point) (1 pt) the number of genes that control the trait. (0 pts) which form of the trait is dominant. (0 pts) the allele frequencies of the various alleles. (0 pts) the relationship of allele frequencies to Mendelian ratios. 1 /1 point 5. A polygenic trait can have (1 point) (0 pts) many possible genotypes, but few possible phenotypes. (1 pt) many possible genotypes, producing many posible phenotypes. (0 pts) fewer phenotypes than most single-gene traits. (0 pts) fewer genotypes than most single-gene traits. 1 /1 point The final score is 5/5 (100%).
