I. Standards
Genetics
Mutation and sexual reproduction lead to genetic variation in a population. As a basis for
understanding this concept:
1. 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.
2. Students know only certain cells in a multicellular organism undergo meiosis.
3. Students know how random chromosome segregation explains the probability that a particular
allele will be in a gamete.
4. Students know new combinations of alleles may be generated in a zygote through the fusion of
male and female gametes (fertilization).
5. Students know why approximately half of an individual's DNA sequence comes from each
parent.
6. Students know the role of chromosomes in determining an individual's sex.
7. Students know how to predict possible combinations of alleles in a zygote from the genetic
makeup of the parents.
A multicellular organism develops from a single zygote, and its phenotype depends on its
genotype, which is established at fertilization. As a basis for understanding this concept:
8. Students know how to predict the probable outcome of phenotypes in a genetic cross from the
genotypes of the parents and mode of inheritance (autosomal or X-linked, dominant or recessive).
9. Students know the genetic basis for Mendel's laws of segregation and independent assortment.
II. Objectives: Answer on a separate piece of paper. Answers do not need to be in complete sentences,
however your answers must be thorough.
YOU MUST BE ABLE TO:
1. Describe Mendel’s experiments.
2. Explain how meiosis is related to Mendel’s laws.
3. Identify the different phases of mitosis and meiosis.
4. Describe differences between meiosis and mitosis.
5. Identify the products of meiosis and mitosis.
6. Make a punnett square using whichever trait you would like. Find the genotypic and phenotypic ratios.
8. Make a dihybrid cross using any 2 traits. Give the phenotypic ratio.
III. Vocabulary: Define vocab words and know how to apply them.
