What is Heredity?

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

• The passing of traits from parent to offspring

• sequence of DNA that codes for a protein and thus determines a trait

• The study of heredity

What is an allele?

• physical characteristics of an organism

• An gene that is always expressed

• sex cell

• form of a gene

What is a gamete?

• physical characteristics of an organism

• An gene that is always expressed

• sex cell

• form of a gene

What is a phenotype?

In genetics, what does it mean to be dominant?

• physical characteristics of an organism

• An allele that is always expressed

• sex cell

• form of a gene

What is meant by heterozygous?

• An organism's genetic makeup, or allele combinations.

• having two identical alleles for a trait

• having two different alleles for a trait

• An allele that is masked when a dominant allele is present

What is meant by recessive?

• An organism's genetic makeup, or allele combinations.

• having two identical alleles for a trait

• having two different alleles for a trait

• An allele that is masked when a dominant allele is present
