What is a clone

Organisms that are exact genetic types

What are the difference between haploid and diploid

Haploid cells contain only one set of chromosomes; haploid cells are formed by the process of meiosis. Diploid contains two sets of chromosomes; diploid cells undergo mitosis.

What is the diploid chromosome number for humans?

46

Egg and sperm cells are haploid or diploid?

haploid

Meiosis 1 or 2: Homologous chromosomes pair and form synapses

Prophase 1

Meiosis 1 or 2: Bivalents align at metaphase plate

Metaphase 1

Meiosis 1 or 2: Two complete daughter cells form

Telophase 1

Meiosis 1 or 2: Nuclear membrane disappears

Prophase 1

Meiosis 1 or 2: Nuclear membrane reforms

Telophase 1

Meiosis 1 and 2: Chromosomes move to separate poles

Anaphase 1

At the end of meiosis 2, each cell contains how many chromosomes?

23 chromosomes

Name 2 errors that can occur during meiosis
