Which statement describes the relationship between chromosomes, genes, and alleles?

a.
alleles move genes to a specific location on a chromosome.

b.
genes bind to sites on a chromosome. these sites are called alleles.

c.
alleles cause mutations, which are genes on part of a chromosome.

d.
alleles are different variations of a gene. genes are the specific sections of a chromosome.

D is the best of the options given. Alleles are different versions of a gene. A given gene is localized (located) in a specific location on a chromosome. A chromosome consists of genes. There are many different versions of genes out there. (i.e. the gene for hair color could have an allele coding for black, blond, red, brown, etc. colored hair. That allele would be where you find the gene for hair color on the chromosome.) Hope this helps! :)

The answer is c i just finished taking the test
