Mendel and his Peas

Front

What is a true-breeding plant?

Back

A true-breeding plant is one that, when self-pollinated, produces offspring that are identical to the parent in terms of specific traits.

Front

What is heredity?

Back

Heredity is the passing of genetic traits from parent to offspring.

Front

What is a recessive trait?

Back

A recessive trait is a genetic trait that can be masked by a dominant trait and may reappear in the second generation after disappearing in the first.

Front

What is the ratio of dominant to recessive traits in the second generation when a first-generation plant self-pollinates?

Back

The ratio is 3:1, meaning for every three plants with the dominant trait, there is one plant with the recessive trait.

Front

What is self-pollination?

Back

Self-pollination occurs when the sperm from one plant fertilizes the eggs of the same plant.

Front

What is cross-pollination?

Back

Cross-pollination is the transfer of pollen from the flower of one plant to the flower of another plant.

Front

What is a dominant trait?

Back

A dominant trait is a genetic trait that is expressed in the phenotype even when only one copy of the gene is present.

Front

What is a hybrid plant?

Back

A hybrid plant is the offspring resulting from the cross-breeding of two different true-breeding plants.

Front

What is the significance of Mendel's experiments with pea plants?

Back

Mendel's experiments established the basic principles of heredity and genetics, demonstrating how traits are inherited.

Front

What are alleles?

Back

Alleles are different forms of a gene that can exist at a specific locus on a chromosome.
