Genetics I

Genetics is

• the passing of traits from parents to offspring

• a factor that controls traits

• the scientific study of heredity

• each different form of a gene

Allele is

• a physical characteristic of organisms

• a factor that controls traits

• an organism with two different alleles for a trait

• each different form of a gene

Trait is

• a factor that controls traits

• physical characteristics of organisms

• an allele whose trait is hidden in the presence of a dominant allele

• each different form of gene

The father of modern genetics is

• Gregor Jackson

• Robert Hooke

• Gregor Mendel

• Genetics Mendel

An organism's physical appearance

• phenotype

• genotype

• homozygous

• heterozygous

An organism's genetic makeup, or allele combinations

• phenotype

• genotype

• homozygous

• heterozygous

An organism that has two identical alleles for a trait

• phenotype

• genotype

• homozygous

• heterozygous

An organism that has two different alleles for a trait

• phenotype

• genotype

• homozygous

• heterozygous

An organism with two different alleles for a trait

• homozygous dominate

• homozygous recessive

• hybrid

• homozygous

What can a Punnett square be used to determine?

• The possible combinations of alleles in offspring

• What an offspring will look like

• The height of offspring

• Genetic heritage
