Note from the author:

This formative makes use of the Classical Genetics module from the "DNA Learning Center, Cold Spring Harbor Laboratory. Each of the different concepts and animations are linked in order to focus students on the content they should gather crom each section. After each concept/animation pair has been studied, I added "knowledge checks" which helps both the teacher and students gauge their understanding.

Mendelian Genetics Guided Notes

Mendelian Genetics Guided Notes

Children resemble their parents.

What are some of the useful traits that humans have accentuated by controlled mating?

What is a gene?

Why did Mendel work with peas?

What is cross fertilization?

Knowledge check: Gregor Mendel used pea plants to study inheritance. If you wanted to do the same thing what would you need to do? Check all that apply

Knowledge check: Mendel grew his pea plants in a small garden. He controlled the growing conditions as much as possible. Why is this important?

Genes come in pairs

What did Mendel conclude from his experiments?

What is a phenotype?

What are the seven traits of pea plants that Mendel worked with? Check all that apply

How many phenotypes does each trait have?

What is an allele?

What is a genotype?

What is a purebred?

Knowledge check: You want to repeat Mendel’s experiments with an eighth trait. You choose flower color. Pea plants have flowers that are white or colored. To get a pure-bred colored flower you start with a colored flower plant. What should you do next?

Knowledge check: If in the second generation you still got some white flowers, what should you do next to get a colored pure-bred plant?

Knowledge check: How many times do you need to keep self-fertilizing the colored plants to get a purebred colored plant?

Genes don’t blend

In Mendel’s experiment, did the pea plants produce offspring with blended traits?

If a “puffed” pod purebred pea is crossed with a “pinched” pod purebred pea, will the offspring be “semi-puffed”?

Knowledge check: If a pure-bred tall plant is crossed with a pure-bred short plant, the offspring will be:

Some genes are dominant

What is a dominant trait?

What is a recessive trait?

What does the term homozygous mean?

What does the term heterozygous mean?

What happens to the recessive allele in a heterozygous offspring?

Knowledge check: If the yellow allele is dominant (Y) and the green allele is recessive (y), what are the possible genotypes a yellow the offspring? Check all that apply

Knowledge check: If the yellow allele is dominant (Y) and the green allele is recessive (y), what are the possible genotypes of a green offspring?
