Mendelian Genetics Vocabulary

Gregor wants to understand why his pea plants have different traits. He studies how these traits are passed on. What is the branch of science he is working on?

• Biology

• Genetics

• Botany

• Chemistry

Ana observes that her dimples are similar to her father’s. This is an example of:

• Environment

• Mutation

• Heredity

• Nutrition

In an experiment, a scientist finds the instructions for flower color in pea plants. These instructions are called:

• Hormones

• Genes

• Cells

• Enzymes

Mendel used plants that reproduce quickly and have clear traits for his studies. What plant did he use?

• Corn

• Tomato

• Pea plant

• Rose

In Mendel's experiment, the two original plants he used were called the:

• Offspring

• Test generation

• Parental generation

• Final generation

When Mendel crossed tall and short pea plants, all offspring were tall. These first offspring are called:

• F2 generation

• F1 generation

• Parent generation

• T1 generation

After crossing the F1 tall plants, some short plants reappeared. These plants are part of which generation?

• Parental

• First filial

• Second filial

• Recessive

A farmer wants to know if a tall plant is purebred or hybrid. He crosses it with a short plant. What kind of cross is this?

• Punnett cross

• Test cross

• Self-pollination

• Random mating

A student crosses two different pea plants. The offspring shows traits from both parents. This offspring is a:

• Clone

• Purebred

• Hybrid

• Mutation

If a plant has two identical alleles for flower color, we call it:

• Heterozygous

• Hybrid

• Homozygous

• Inherited
