5 True/False questions
How is meiosis different from mitosis? → Mitosis can be a form of asexual reproduction, does not change the number of chromosomes, and makes two identical diploid cells. Meiosis is a step in sexual reproduction, cuts chromosomes in half, and makes four different haploid cells.
Heterozygous → term used to refer to chromosomes in which one set comes from the male parent and one set comes from the female parent
Zygote → a fertilized egg
Probability → the likelihood that a particular event will occur
Explain how to determine the gametes for a dihybrid cross when the parent gamete is TtYy → Alleles of different genes tend to be inherited together when those genes are on the same chromosome.
