Correct Verified Answers
Which type of reproduction creates offspring with the highest amount of genetic
diversity, sexual or asexual reproduction? Why?
✓ Sexual reproduction (fusion of haploid gametes to form diploid zygote) because
asexual reproduction produces offspring that are genetically identical to parent
What is budding?
✓ offspring form on or in the parent via mitosis
✓ when fully formed, offspring break free of the parent
✓ ex/ occurs in hydra
What is fission?
✓ parent splits in two
✓ ex/ occurs in anemones
What is parthenogenesis?
✓ female offspring develop from unfertilized eggs
✓ ex/ occurs in lizards
What occurs for external fertilization to be successful?
✓ occurs in a moist environment
✓ union of sperm and eggs require cooperative behavior
✓ produce and release many gametes

, Top Mark Questions and Correct Verified Answers
Internal fertilization
✓ Fewer eggs
✓ require specialized reproductive systems for the transport of gametes and
copulation
✓ gonads produce the gametes
✓ several tubes and glands to transport and protect gametes
Which hormones are produced by the hypothalamus and anterior pituitary that triggers
puberty in both male and female humans?
✓ LH (leuteinizing hormone)
✓ FSH (follicle-stimulating hormone)
✓ produce testosterone in males or estradiol in females
What are the terms used to describe the cells produced in each stage of male
gametogenesis?
✓ spermatogonium (2n) --> primary spermatocyte (2n) --> secondary spermatocyte
(n) --> spermatids (n) --> mature sperm cells (n)
What occurs between each stage of male gametogenesis?
✓ mitosis and differentiation
✓ meiosis I
✓ meiosis II
How many functional gametes are produced from one diploid germ cell in male
gametogenesis?
✓ 4

In what structure do sperm cells mature, become motile, and gain the ability to
fertilize?

What are the terms used to describe the cells produced in each stage in female
gametogenesis?
