What type of cell is formed by meiosis?

Back

Sperm cells (and egg cells in females) are formed by meiosis.

Front

What is the genotype of a white flower if red (R) is dominant over white (r)?

Back

The genotype must be rr for the flower to be white.

Front

What does the term 'genotype' refer to?

Back

The exact genetic makeup of an organism, such as RR, Tt, or rr.

Front

What are alleles?

Back

Alleles are alternate or different genes that code for the same trait.

Front

What is the result of mitosis in terms of cell identity?

Back

In mitosis, the two resulting cells are identical to the starting cell and identical to each other.

Front

What is the difference between meiosis and mitosis?

Back

Meiosis results in four genetically diverse cells, while mitosis results in two identical cells.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What does homozygous mean?

Back

An organism is homozygous for a trait if it has two identical alleles for that trait.

Front

What does heterozygous mean?

Back

An organism is heterozygous for a trait if it has two different alleles for that trait.

Front

What is the purpose of meiosis?

Back

The purpose of meiosis is to produce gametes (sperm and egg cells) for sexual reproduction.
