Front

What are gamete cells?

Back

Gamete cells are reproductive cells (sperm and egg) that are haploid, meaning they contain half the number of chromosomes of somatic cells.

Front

How many chromosomes do humans have?

Back

Humans typically have 46 chromosomes, arranged in 23 pairs.

Front

What is the primary purpose of meiosis?

Back

The primary purpose of meiosis is to produce gametes for sexual reproduction, ensuring genetic diversity.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is interphase in meiosis?

Back

Interphase is the phase where the cell prepares for division, including DNA replication, and occurs once before meiosis begins.

Front

What are somatic cells?

Back

Somatic cells are all body cells except for gametes; they are diploid, containing two sets of chromosomes.

Front

What is a zygote?

Back

A zygote is the fertilized egg formed when a sperm cell fertilizes an egg cell, and it undergoes mitosis to develop.

Front

What is the significance of crossing over in meiosis?

Back

Crossing over increases genetic variation by exchanging genetic material between homologous chromosomes during meiosis.

Front

What are homologous chromosomes?

Back

Homologous chromosomes are pairs of chromosomes, one from each parent, that are similar in shape, size, and genetic content.

Front

What is the end result of meiosis?

Back

The end result of meiosis is four haploid gametes, each genetically unique.
