Genetics
2. Mutation and sexual reproduction lead to genetic variation in a population. As a basis for
understanding this concept:
a. Students know meiosis is an early step in sexual reproduction in which the pairs of
chromosomes separate and segregate randomly during cell division to produce gametes
containing one chromosome of each type.
b. Students know only certain cells in a multicellular organism undergo meiosis.
c. Students know how random chromosome segregation explains the probability that a
particular allele will be in a gamete.
d. Students know new combinations of alleles may be generated in a zygote through the fusion
of male and female gametes (fertilization).
e. Students know why approximately half of an individual's DNA sequence comes from each
parent.
f. Students know the role of chromosomes in determining an individual's sex.
g. Students know how to predict possible combinations of alleles in a zygote from the genetic
makeup of the parents.

Objective
1. Analyze how meiosis maintains a constant number of
chromosomes within a species.
2. Infer how meiosis leads to a variation in a species.
3. Relate Mendel’s laws of heredity to the events of meiosis.
