DNA has a sequence of nucleotides with different bases to determine traits of an organism. Scientists can genetically modify these sequences in order to give an organism more desirable traits. Do you think gene modification is ethical? Why or why not?

In a relatively small iguana population the allelic frequency is tracked for three generations. webbing is a recessive allele; no webbing is the dominant allele. during one very rainy spring and summer, a flood washes all the iguana without webbed feet out to sea. by the fall, and three generations later, you have the gene pool seen here.

What do we call an individual that has inherited two identical alleles for the same trait? a.homozygous b.heterozygous c.monozzygous
