Summary
This document is a genetics study guide for a midterm exam. It contains key terms like dominant, recessive, homozygous, and heterozygous, and a sample dataset analyzing pea flower color from Mendel's research. The guide details Mendel's laws of segregation and independent assortment, as well as modern genetic concepts like linked genes and multiple alleles.

Unit 3 - Genetics Study Guide FOR THE MIDTERM-ONLY COMPLETE SECTIONS 3.1 -3.3 Key Terms to Know 1. Know these key terms: (start by highlighting the ones you’re unsure/confused about) Gregor Mendel Dominant Law of Segregation Sex Chromosome Homozygous Recessive Law of Ind. Assort.

Dominance DNA Fingerprint Allele Genetic Variation Codominance CRISPR Genotype Crossing Over Multiple Alleles Gene Therapy Phenotype Linked Genes Autosome GMO 3.1 - Mendel & Modern Genetics 1. Below is a sample of Mendel’s data analyzing pea flower color. Describe the simple observations Mendel made about the data. Remember, he didn’t know or use terms like dominant/recessive, DNA, Genes, etc. 2. The theory of Evolution was published in 1859. The first model of DNA was built in 1953. Gregor Mendel officially published his results in 1865. Mendel did not know about Charles Darwin’s book when he started his experiments but he DID get a copy of his book Origin of Species and read it before he published his own work. Below is a list of terms/ideas that Mendel’s experiments are NOW used to explain. Draw a concept map using Google Draw (or on paper & take a pic/upload it here) that shows the relationship between these terms: ❏ Gene ❏ Allele ❏ Dominant ❏ Recessive ❏ Genotype ❏ Phenotype ❏ Linked Genes ❏ Heterozygous ❏ Gametes ❏ Meiosis ❏ Homozygous ❏ Haploid ❏ Diploid ❏ Zygote ❏ Unlinked Genes 3.2 - Important Terminology 1. Some of the most important terms for understanding the unit are in the table below. Be sure to understand the basics of each term and provide examples to demonstrate your understanding. Term Description Examples Homozygous Heterozygous Dominant Recessive Genotype Phenotype 3.3 - Heredity 1. Describe how reproduction & gamete formation through Meiosis can lead to genetic diversity: 2. Describe the concept of linked genes in your own words:
