Front

What process results in 4 haploid daughter cells?

Back

Meiosis is the process that results in 4 haploid daughter cells.

Front

What promotes more genetic diversity during meiosis?

Back

Independent Assortment promotes more genetic diversity due to the random separation of genes on separate chromosomes.

Front

What occurs when chromosomes fail to separate during meiosis?

Back

Nondisjunction occurs when chromosomes fail to separate during meiosis.

Front

What phase do cells spend most of their lives in, preparing to divide?

Back

Cells spend most of their lives in Interphase, where DNA replicates and organelles are doubled.

Front

What does homozygous mean?

Back

Homozygous means that both alleles are the same.

Front

What does heterozygous mean?

Back

Heterozygous means that the alleles are different.

Front

What is the main purpose of meiosis?

Back

The main purpose of meiosis is to produce gametes (sperm and eggs) with half the number of chromosomes.

Front

What is crossing over?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during meiosis.

Front

What is the difference between haploid and diploid?

Back

Haploid cells have one set of chromosomes, while diploid cells have two sets.

Front

What is fertilization?

Back

Fertilization is the process where a sperm cell and an egg cell combine to form a zygote.
