Reproductive Physiology

Question 1

when are dyads visible

Answer 1

both mitosis and meiosis

Question 2

when are tetrads visible

Answer 2

meiosis only

Question 3

the product is two diploid daughter cells genetically identical to the mother cell

Answer 3

mitosis only

Question 4

the product is four haploid daughter cells quantitatively and qualitatively different from the mother cell

Answer 4

meiosis only

Question 5

involves the phases prophase, metaphase, anaphase, and telophase

Answer 5

both mitosis and meiosis

Question 6

occurs throughout the body

Answer 6

mitosis only

Question 7

occurs only in the ovaries and testes

Answer 7

meiosis only

Question 8

provides cells for growth and repair

Answer 8

mitosis only

Question 9

homologues synapse, crossovers are seen

Answer 9

meiosis only

Question 10

chromosomes are replicated before the division process begins

Answer 10

both mitosis and meiosis

Question 11

provides cells for perpetuation of the species

Answer 11

meiosis only

Question 12

consists of two consecutive nuclear divisions without chromosomal replication occurring before the second division

Answer 12

meiosis only

Question 13

what occurs during synapsis

Answer 13

pairing of homologous chromosomes

Question 14

why is crossover important

Answer 14

it introduces variability in the daughter cells because homologues separate and exchange parts

Question 15

what ere homologous chromosomes

Answer 15

egg and sperm chromosomes that carry genes for the same traits(one paternal and one maternal)

Question 16

primitive stem cell

Answer 16

spermatogonium

Question 17

haploid

Answer 17

secondary spermatocyte, spermatid, sperm

Question 18

provides nutrients to developing sperm

Answer 18

sustentocyte

Question 19

products of meiosis 2

Answer 19

spermatid

Question 20

product of spermiogenesis

Answer 20

sperm

Question 21

product of meiosis 1

Answer 21

secondary spermatocyte

Question 22

why are spermatids not considered functional gametes

Answer 22

they are nonmotile, too much superfluous cytoplasm

Question 23

what is spermatogenesis

Answer 23

formation of haploid gametes by the male

Question 24

what is spermiogenesis

Answer 24

sloughing off excessive spermatid cytoplasm to form a motile functional sperm

Question 25

why is the life span of sperm so short

Answer 25

no cytoplasm in which to store nutrients

Question 26

what is a follicle

Answer 26

structure consisting of a capsule of follicle cells that encloses a developing gamete
