Asexual reproduction – Involves one parent; offspring are genetically identical.
Sexual reproduction – Involves two parents; offspring have genetic variation

Question 3

what is sexual reproduction?

Answer 3

sexual reproduction involves the fusion of male and female gametes (sperm and egg), resulting in a zygote with genetic material from both parents

Question 4

where does fertilization occur in humans?

Answer 4

fertilization typically occurs in the fallopian tube

Question 5

Answer 7

implantation is when the zygote (now a blastocyst) embeds itself into the uterine lining to begin developing into an embryo

Question 8

what is the difference between an embryo and a fetus?

Answer 8

embryo: From fertilization to 8 weeks of development.
Fetus: From 8 weeks until birth

Question 9

what is gestation?

Answer 9

gestation is the period of development from fertilization to birth, lasting about 9 months in humans

Question 10

what triggers labor?
