EOC 23 Cellular Reproduction

Front

What is mitosis?

Back

Mitosis is a type of cell division that results in two identical diploid daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

Meiosis is a specialized form of cell division that produces four genetically different haploid gametes, each with half the number of chromosomes of the parent cell.

Front

What is the main purpose of mitosis?

Back

The main purpose of mitosis is for growth, repair, and asexual reproduction in organisms.

Front

What is the main purpose of meiosis?

Back

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

Front

Define haploid.

Back

Haploid refers to a cell that contains one complete set of chromosomes (n), typical of gametes.

Front

Define diploid.

Back

Diploid refers to a cell that contains two complete sets of chromosomes (2n), typical of somatic cells.

Front

What is crossing over?

Back

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

Front

What is independent assortment?

Back

Independent assortment is the random distribution of maternal and paternal chromosomes into gametes during meiosis, contributing to genetic diversity.

Front

What is random fertilization?

Back

Random fertilization refers to the random combination of gametes during fertilization, which increases genetic variation in offspring.

Front

What is the significance of prophase I in meiosis?

Back

Prophase I is significant because it is the stage where homologous chromosomes pair up and crossing over occurs, leading to genetic recombination.
