An organism that contains more than one cell

Question 7

Inherited Traits

Answer 7

Traits that are inherited from parent to offspring

Answer 9

The male reproductive cell

Question 10

Autosomal

Answer 10

A chromosome that is not a sex chromosome

Question 11

Complete Dominance

Answer 11

Where the dominant allele completely masks the effect of the recessive allele

Question 12

Dihybrid Cross

Answer 12

A cross between two individuals with two observed traits that are controlled by two distinct genes

Question 13

F1 (First Filial)

Answer 13

The first generation of offspring

Question 14

The genetic makeup of an organism

Question 16

Genotypic Ratio

Answer 16

The ratio of the number of times a genotype would appear in the offspring after a test cross

Question 17

Hardy-Weinberg Conditions

Answer 17

Conditions for the Hardy-Weinberg Equilibrium such as no mutation, random mating, no gene flow, infinite population size, and no selection.

Question 18

Hardy-Weinberg Equilibrium

Answer 18

A law that states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.

Question 19

Incomplete Dominance

Answer 19

When the result of two alleles is a mix of the two rather than one allele only being present
