The passing of traits from parent to offspring is known as

• Heredity

• Genetics

• Hybrid

• Probability

Who was the Austrian monk whose experiments earned him the title of "Father of Genetics?"

• John Locke

• Issac Newton

• Gregor Mendel

• Albert Einstein

The study of heredity and the variation of inherited characteristics

• Gene

• Genetics

• Meiosis

• Hybrid

What is a phenotype?

• The genetic make up (code)

• The physical trait

An allele whose trait only shows up when no dominant allele is present

• Hidden allele

• Dominant allele

• Recessive allele

• Present allele

What does heterozygous mean?

• An organism that has the same genes for a trait (TT or tt)

• An organism that has different genes for a trait (Tt)

• When neither gene is fully dominant; offspring is a mixture of both

• The different forms of a trait (hair color--> brown, blonde, red

What is the definition of genotype?

• The physical expression of a trait

• The genetic combination of alleles

• The genes on a DNA strand

Having two of the same genes for the trait (sometimes called purebred or pure)

• Homozygous

• Hetrozygous

• Protein

• Chromosome

Having two different genes for a trait (sometimes called hybrid)

• Protein

• Homozygous

• Heterozygous

• Genotype
