Introduction to Meiosis exam Flashcards

A two-part cell division process that results in four genetically diverse haploid gametes.

To produce gametes for sexual reproduction and contribute to genetic diversity.

Homologous chromosomes are separated, reducing the chromosome number by half.

The second division in meiosis where sister chromatids are separated, maintaining ploidy.

A cell with two copies of every chromosome that acts as the precursor for making gametes.

A cell with a single set of chromosomes, represented by 'n'.

Another term for meiosis I, where the chromosome number is reduced.

Another term for meiosis II, where the chromosome number remains the same.

It contributes to variation in offspring, which is important for evolution and adaptation.

The process that follows meiosis I and II, dividing the cytoplasm to form separate cells.

Sex cells, such as sperm and eggs, produced through meiosis.

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

DNA replication.

Meiosis produces four genetically diverse haploid cells, while mitosis produces two identical diploid cells.

The random distribution of homologous chromosomes during meiosis I, contributing to genetic diversity.

It exchanges genetic material between homologous chromosomes, increasing genetic diversity.

Two haploid cells with half the original chromosome number.

Four haploid cells, each genetically distinct.

The variety of different genetic makeups within a population, enhanced by meiosis.

It generates genetic variation, which is essential for natural selection and evolution.

The number of sets of chromosomes in a cell.

To produce gametes that combine during fertilization to form a genetically unique offspring.
