In a population, the sum of the relative frequencies of all alleles for a particular trait is
crossing-over.
fewer phenotypes.
the number of genes that control the trait.
two phenotypes.
gene shuffling and mutations.
does not change the gene pool’s allele frequencies.
no changes in the relative frequencies of alleles in the gene pool.
equal to 100 percent.
single-gene trait that has two alleles and that shows a simple dominant-recessive pattern will result in
crossing-over.
fewer phenotypes.
the number of genes that control the trait.
two phenotypes.
gene shuffling and mutations.
does not change the gene pool’s allele frequencies.
no changes in the relative frequencies of alleles in the gene pool.
equal to 100 percent.
Compared to a polygenic trait, a single-gene trait tends to have
crossing-over.
fewer phenotypes.
the number of genes that control the trait.
two phenotypes.
gene shuffling and mutations.
does not change the gene pool’s allele frequencies.
no changes in the relative frequencies of alleles in the gene pool.
equal to 100 percent.
nterbreeding among members of a population results in
crossing-over.
fewer phenotypes.
the number of genes that control the trait.
two phenotypes.
gene shuffling and mutations.
does not change the gene pool’s allele frequencies.
no changes in the relative frequencies of alleles in the gene pool.
equal to 100 percent.
The two main sources of genetic variation are
crossing-over.

The number of phenotypes produced for a given trait depends upon
crossing-over.
fewer phenotypes.

no changes in the relative frequencies of alleles in the gene pool.
equal to 100 percent.
Gene shuffling includes the independent movement of chromosomes during meoisis as well as
crossing-over.
