BIO181 - Meiosis Exam Questions Answered Correctly (Already Passed)
When two haploid gametes unite, they create a diploid cell called a . - Answers zygote
The process by which two haploid gametes unite to form a zygote is called _______________
reproduction. - Answers sexual
One of the problems with sexual reproduction is that chromosome number has to be maintained from
one generation to the next generation. For that to happen, sexual reproduction requires a fertilization
event in which two __________ gametes unite to create a _________ cell called a zygote. - Answers
haploid; diploid
How many chromosomes does a human gamete possess? - Answers 23
Which of these is one of the significant results of meiosis? - Answers It creates haploid gametes for
sexual reproduction.
A zygote is created when two haploid cells, called _____________ , fuse. - Answers gametes
Meiosis is the process by which _____________ cells are produced from a cell that was originally diploid.
- Answers haploid
New individuals of a species are created by mixing genetic material from two parents in a process called
- Answers sexual reproduction.
Which type of process requires a fertilization event in which two haploid gametes unite to create a
diploid cell called a zygote? - Answers Sexual reproduction
The sorting that occurs during ______ separates homologues from each other. - Answers meiosis I
A human __________ contains only 23 chromosomes. - Answers gamete, sperm, egg, haploid cell, or sex
cell
True or false: Meiosis is very important because it creates diploid daughter cells for sexual reproduction.

A bivalent is formed when ____________ pairs of sister chromatids associate with each other, lying side
by side. - Answers homologous
