Heredity and Genetics Vocab

What is heredity?

• The study of how traits are passed from parents to offspring

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor

• A genetic factor that is blocked by the presence of a dominant factor

What is genetics?

• The study of how traits are passed from parents to offspring

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor

• A genetic factor that is blocked by the presence of a dominant factor

What is a dominant trait?

• The study of how traits are passed from parents to offspring

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor; it is stronger

• A genetic factor that is blocked by the presence of a dominant factor; it is weaker

What is a recessive trait?

• The study of how traits are passed from parents to offspring

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor

• A genetic factor that is blocked by the presence of a dominant factor

What is a gene?

• A section on a chromosome that has genetic information for the trait

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor

• A genetic factor that is blocked by the presence of a dominant factor

What are alleles?

• The different forms of a gene

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor

• A genetic factor that is blocked by the presence of a dominant factor

What is phenotype?

• How a trait appears or is expressed

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor

• A genetic factor that is blocked by the presence of a dominant factor

What is genotype?

• The two alleles that control the phenotype of a trait

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor

• A genetic factor that is blocked by the presence of a dominant factor

What does homozygous mean?

• When the two alleles of a gene are the same

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor

• A genetic factor that is blocked by the presence of a dominant factor

What does heterozygous mean?

• When the two alleles of a gene are different

• The passing of traits from parents to offspring

• A genetic factor that blocks another genetic factor

• A genetic factor that is blocked by the presence of a dominant factor
