Some eukaryotes reproduce asexually,

and some reproduce sexually

T or F

True

At the conclusion of crossing-over, 

genetic recombination has occured

T or F

True

In sexual reproduction, two parents

each form haploid cells, which

join to form offspring

T or F

True

The two cells produced during the first

cytokinesis in female animals

are approximately equal in

size and contain the same amount of cytoplasm

T or F

False

Meiosis in female animals results in the

same number of ova as sperm

that were produced by meiosis

in the male

T or F

False

In most animals, including humans,

meiosis produces sperm and egg cells

T or F

True

The process by which sperm are produced in

male animals is called 

spermatogenesis

T or F

True

In asexual reproduction, two parents

each pass copies of all of their

cells to their offspring

T or F

False

The exchange of segments of DNA between

the members of a pair of chromosomes 

is call crossing

or

acts as a source of variations within a species

Acts as a source of variations within a species

Crossing-over occurs

during fertilization

or

during prophase I
