Meiosis

Front

The chromosomes that pair up during meiosis, are called __________ chromosomes.

Back

homologous

Front

What causes genetic variation in meiosis?

Back

crossing over of chromosomes

Front

If the Diploid number of Carrots is 18, the haploid number is __________.

Back

9

Front

What kind of cells are made in MEIOSIS?

Back

Haploid cells

Front

When homologous chromosomes match up, they form a structure called a ___________.

Back

tetrad (pair of chromosomes, one from mom and one from dad)

Front

Define meiosis.

Back

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

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells contain two complete sets of chromosomes (one from each parent), while haploid cells contain only one set of chromosomes.

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 variation.

Front

What is a tetrad?

Back

A tetrad is a structure formed during meiosis when homologous chromosomes pair up, consisting of four chromatids.

Front

What is the role of spindle fibers in meiosis?

Back

Spindle fibers help separate the chromosomes during cell division, ensuring that each new cell receives the correct number of chromosomes.
