Answer 21

The organism’s genetic makeup or allele combinations.

Question 22

Give the definition of a Dominant allele.

Answer 22

An allele whose trait always shows up in the organism when the allele is present, even if there is only one.

Question 23

Give the definition of a Trait.

Answer 23

A characteristic of an organism that can pass on to its offspring through genes.

Question 24

Give the definition of a genome.

Answer 24

Give the definition of Heterozygous.

Answer 28

Having two different alleles for a particular trait. (e.g. Hh- heterozygous)

Question 29
