16
Q

What are the spermtozoa

A

The cells with the head of a haploid and a flagella

17
Q

What is Oogenesis

A

Maturation of oova cells (eggs)
occurs in ovarian follicles

18
Q

What are the polar bodies of oogenesis

A

The smaller useless cells produced in the first and second round of meiosis during the maturation of oova cells.
This happens because the one oova cell needs all of the cell mass because the sperm cell only carries genetic information.

19
Q

What is gondal sex

A

It is sex that is determined by chromosomes
EX: XX or XY

20
Q

What is pheotypic and behavioral sex

A

Sex that is dependent on hormones, can be affected by temperature (reptiles) and social behavior (clown fish)

21
Q

What are Oviparous animals

A

They are animals that lay eggs

22
Q

What are Viviparous animals

A

They are animals that produce fully formed offspring from the body

23
Q

What Ovoviviparous animals

A

Animals which get their nourishment from the yolk but still remain in the mother until birth
EX: sharks

24
Q

What are the primary organs called in reproductive systems

A

Gonads

25
Q

What are the organs that are not the primary organs in the reproductive systems

A

accessory organs
