Question 16

Oogenesis starts with the _.

Answer 16

oogonium

Question 17

The oogonium becomes the _ which will enter meiosis I.

Answer 17

primary oocyte

Question 18

The oogonium becomes the _ which will enter meiosis I.

Answer 18

primary oocyte

The result from this is _ and _.

Answer 19

one secondary oocyte and one polar body

Question 20

The result from this is _ and _.

Answer 20

one secondary oocyte and one polar body

Question 21

The secondary oocyte will then enter meiosis II to produce _ and _.

Answer 21

one egg cell and another polar body;

Question 22

The secondary oocyte will then enter meiosis II to produce _ and _.

Answer 22

one egg cell and another polar body;

Question 23

The first polar body divides to form _.

Answer 23

two polar bodies

Question 24

Polar bodies cannot be fertilized by a sperm. Thus, each cycle of cogenesis produces _, all from one oogonium.

Answer 24

one egg cell and three polar bodies

Question 25

Polar bodies cannot be fertilized by a sperm. Thus, each cycle of cogenesis produces _, all from one oogonium.

Answer 25

one egg cell and three polar bodies

Answer 26

fertilization

Question 27

The resulting fertilized egg is _, with half of the chromosomes coming from each parent.

Thus, it is in fertilization where the original _ number of chromosomes in a species is restored.

Answer 27

diploid
