Question 1

Genetics

Answer 1

The science of hereditary. Began with Mendel.

Question 2

Heredity

Answer 2

The passing of traits to the next generation.

Question 3

Allele

Answer 3

Alternative form of a single gene passed from generation to generation.

Question 4

Dominant

Answer 4

Form of the trait that appeared in the F1 generation.

Question 5

Recessive

Answer 5

Form of the trait that appeared in the F2 generation.

Question 6

Homozygous

Answer 6

Organism with two of the same alleles for a particular trait.

Question 7

Heterozygous

Answer 7

Organism with two different alleles for a particular trait.

Question 8

Genotype

Answer 8

Organism’s allele pairs.

Question 9

Phenotype

Answer 9

Observable characteristic or outward expression of an allele pair.

Question 10

Law of Segregation

Answer 10

States that two alleles for each trait separate during meiosis. During fertilization, two alleles for that trait unite.

Question 11

Hybrids

Answer 11

The result of an organism with two different alleles for a particular trait.

Question 12

Law of Independent Assortmant

Answer 12

States that random distribution of alleles occurs during gamete formation. Genes on separate chromosomes sort independently during meiosis.
