STT1083 Activity 1 (G2)

Genetics is the study of

• heredity

• pea plants

• viruses

• Mendel

Heredity describes how ______ are passed down from parents to offspring.

• traits

• food & water

• inheritance & money

• diseases

In Mendel's experiments, the trait for tall stem height in pea plants was recessive.

• False

• True

Mendel studied genetics by cross-pollinating the traits of these types of plants.

• peas

• beans

• celery

• cactus

When Mendel crossed true-breeding purple-flowered plants with white-flowered plants, all the offspring had what coloured plants?

• purple

• white

• pink

• blue

This is because the allele for purple plants is...

• dominant

• recessive

The allele for white flowers is...

• dominant

• recessive

The physical description of an organism's trait is

• phenotype

• genotype

• homozygous

• heterozygous

The combination of alleles that an individual has is

• phenotype

• genotype

• homozygous

• heterozygous

When an individual has two of the SAME alleles for a trait, the genotype is

• phenotype

• genotype

• homozygous

• heterozygous
