Science is the study of the nature and behaviour of natural things and the knowledge that we obtain about them. A science is a particular branch of science such as physics, chemistry, or biology. Physics is the best example of a science which has developed strong, abstract theories.

Five key descriptors for the scientific method are: empirical, replicable, provisional, objective and systematic.

aa. Aa. AA. Zebra mussels have the following genotypes and phenotypes. Which cross would produce the greatest number of heterozy

lyudmila [28]

Answer: A (AA x aa)

Explanation:

In option (A) both of the parent mussels are homozygotes, for alleles "a" and "A" respectively. Therefore, every single one (100%) of their offspring would be expected to be Aa heterozygotes. Combinations (B) and (D) yield a lower proportion of heterozygotes (50%), and combination (C) yields none at all. Punnett squares follow:

(A)

| A A

a | aA aA

(B)

| A a

A | AA Aa

a | aA aa

(C)

| A A

A | AA AA

(D)
