200

How many parents are needed for asexual reproduction?

1

300

During meiosis, homologous chromosomes exchange genetic material. what does this change of material do? A. increases genetic variation B. reduces the diploid number to the haploid number

100

How many functional gametes are produced in the male as a result of meiosis?

4

200

What kind of cell does meiosis begin with? A. haploid B. diploid

B. diploid

300

What are 2 advantages for asexual reproduction?

Less time and energy used to find a mate.

400

A. Haploid

300

The passing of physical characteristics from parent to offspring.

Heredity

400

500

Sexual reproduction provides ________. This possibly allows the offspring to better adapt to changing environments.

genetic variation

5

100

If the environment changes for an asexual organism, it could possibly do this since there's no genetic variation from its parent.

Possibly die if it cannot adapt.

200

When Sperm & egg unite.

Fertilization

300

What are 2 disadvantages to asexual reproduction?

Populations are limited to specific conditions and populations have no genetic variation, therefore, they are slower to adapt to new environmental changes.

400

hydra reproduce by....which is when an offspring grows from the parent.

budding

500

What are some disadvantages of sexual reproduction?

Takes time to find a mate and uses energy. Requires 2 parents.
