Genetics Review

The study of how traits are inherited is called:

• heredity

• genetics

• chemistry

• dominance

The passing of traits from parents to offspring is called:

• heredity

• genetics

• chemistry

• dominance

In the mid-1800s, Gregor Mendel studied the inheritance of different traits in:

• human eyes

• human earlobes

• pea plants

• bacteria

Gregor Mendel is known as the Father of Genetics because he proposed one of the earliest theories on:

• dominant and recessive traits

• the structure of DNA

• multiple alleles

• genetic engineering

A trait that can hide another trait is called:

• dominant

• recessive

• allele

• pedigree

A trait that can be hidden by another trait is called:

• dominant

• recessive

• homozygous

• heterozygous

Every gene in an organism's DNA can have one of several nitrogen base sequences. These different forms of the same gene are known as:

• alleles

• pedigrees

• Punnett squares

• chromosomes

Which of these terms means the same as "purebred"?

• homozygous

• heterozygous

• dominant

• recessive

Which of these terms means the same as "hybrid"?

• homozygous

• heterozygous

• dominant

• recessive

A pair of code letters that represents the two genes an organism has for a trait is called a(n):

• genotype

• phenotype

• allele

• inheritance
