WebLesson Plan Grade: 6th-8th. Explore genetic variation through the world of taste in this problem-solving lesson plan. Working both individually and collaboratively, students figure out what kind of tasters they are, what this means about their own genetics, and how genetic mutations can lead to functional differences. WebTo summarize, we learned that sexual reproduction occurs when two haploid gametes fuse together in fertilization, creating a diploid offspring with homologous chromosome pairs. We also learned that the patterns of chromosome inheritance during sexual reproduction lead to genetic variation in families and populations.

WebThese forces all influence the patterns and amounts of genetic variation in natural populations in different ways. Mutation increases genetic variation. Random genetic drift reduces genetic variation. Selection typically reduces variation. However, some forms of selection can maintain genetic variation. For example, frequency dependent or WebHeredity: Inheritance and Variation of Traits Variation in organisms of the same species can be explained by both genetic and environmental factors. In sexual reproduction, both parents contribute half of each chromosome pair to the offspring. This produces a unique combination of genes.
