Gametogenesis

Formation of gametes

2

Spermatogenesis and 64 days. In testes or epidydimis

3

Oogenesis = ?

Ova production in females within the ovaries

Ovulation under control of what hormones

Follicle stimulating hormone. hormonal regulation = ovulation of mature follicle which releases ovum.

What is the ongoing cycle cells undergo

growing, dividing and dying AKA apoptosis.

6

Bacteria undergo

Binary fission = DNA replicates and then cell divide into two. Mitochondria and chloroplast. 20-30 minutes

7

Yeast undergo

Budding = small amount of cell pinches off and then divides into two cells. A clone is produced

8

Paired arrangement of chromosomes are KA. Obtained from what

homologous chromosomes - maternal and paternal derivatives

9

Homologous chromosomes where

Somatic autosomal cells

10

True or False: there is a correlation between the number of chromosomes in a cell and the degree of complexity of the cell division.

false. There is no correlation

11

Asexual reproduction can produce

A clone ie genetically identical organism to their parent organism/cells.

12

What does asexual reproduction not involve?

Meiosis, ploidy reduction or fertilization

13

How many chromosomes in humans?

23 pairs -44 autosomal and then two sex chromosomes.
