meiosis & heredity review

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, producing four haploid gametes from one diploid cell.

Front

What is the main outcome of meiosis?

Back

The main outcome of meiosis is the production of four genetically diverse haploid gametes.

Front

What is a haploid cell?

Back

A haploid cell is a cell that contains one complete set of chromosomes, denoted as n.

Front

What is a diploid cell?

Back

A diploid cell is a cell that contains two complete sets of chromosomes, one from each parent, denoted as 2n.

Front

What is the role of sister chromatids in meiosis?

Back

Sister chromatids are identical copies of a chromosome that are separated during meiosis II.

Front

What is a genome?

Back

A genome is the complete set of genetic material in an organism, including all of its genes.

Front

What is the probability of offspring being homozygous recessive from a cross between a homozygous recessive and a heterozygous parent?

Back

The probability is 1/2.

Front

What happens during interphase?

Back

During interphase, the cell prepares for division by replicating its DNA and organizing its genetic material.

Front

What is the difference between mitosis and meiosis?

Back

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

Front

What is crossing over?

Back

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