Question
White-tailed deer have 70 chromosomes per diploid cell. When white-tailed deer parents have white-tailed deer babies (fawns) via sexual reproduction, those babies also have 70 chromosomes per diploid cell. How is this possible?
Question options:
Fertilization makes a white-tailed deer zygote with 140 chromosomes, and then the 70 dominant chromosomes eliminate the 70 recessive chromosomes
White-tailed deer cells can tell when they have too many or too few chromosomes, and they selectively make or eliminate chromosomes as necessary
Fertilization makes a white-tailed deer zygote with 140 chromosomes, and then meiosis makes the first four white-tailed deer cells having 70 chromosomes each
Meiosis makes white-tailed deer gametes with 35 chromosomes each, and then fertilization makes a white-tailed deer zygote with 70 chromosomes
Fertilization makes a white-tailed deer zygote with 140 chromosomes, but then independent assortment makes half those chromosomes disappear

Explanation / Answer
Answer: Meiosis makes white-tailed deer gametes with 35 chromosomes each, and then fertilization makes a white-tailed deer zygote with 70 chromosomes.
Fertilization (fusion of male and female gamets) results zygote. During gamet formation meiosis take place, in which chromosome number (75) will be rneduced into half (35). Two gametes of white-tailed deer containing 35 chromosomes each fuse and form a zygote containing 70 chromosomes, which ultimately grow into fawn.
