Unit 4 (Cell Cycle, Mitosis vs. Meiosis, Punnett Squares)

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, used for growth and repair.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, producing four genetically diverse gametes.

Front

What is a homozygous dominant genotype?

Back

A homozygous dominant genotype consists of two identical dominant alleles (e.g., AA).

Front

What is a homozygous recessive genotype?

Back

A homozygous recessive genotype consists of two identical recessive alleles (e.g., aa).

Front

What is a Punnett square?

Back

A Punnett square is a diagram used to predict the genetic outcomes of a cross between two organisms.

Front

What is crossing-over in meiosis?

Back

Crossing-over is the exchange of genetic material between homologous chromosomes during prophase I of meiosis, leading to genetic diversity.

Front

How many daughter cells are produced in mitosis?

Back

Mitosis produces 2 daughter cells.

Front

How many daughter cells are produced in meiosis?

Back

Meiosis produces 4 daughter cells.

Front

What is the purpose of DNA replication?

Back

DNA replication is the process of copying the DNA before cell division, ensuring each daughter cell receives an identical set of chromosomes.
