Genetics- wrapping it up (the fastest genetics unit ever)

Explore genetics basics: traits, alleles, and mutations!

May 27, 2020 10 Watch the video TWICE. It is very short. You will use the video to answer questions below. In the video, the feature being discussed was ear shape. Possible traits for ear shape included normal or folded. Susie had a changed gene for the protein that makes cartilage. The gene now made a protein that created a weaker type of cartilage. As a result, the cartilage was too weak to hold the ears up. Mutations are random. Sometimes they don't negatively affect the organism at all. Practice identifying homozygous and heterzygous combinations of alleles (gene versions). Remember:Homozygous= the SAME allele is provided by each parentHeterozygous= each parent hands down a DIFFERENT versionWe are going to be consistent with Amplify, which labels the allele using number (like P1 and P2). You may see this differently at a later time, but no worries now:) Homozygous H2H2 T1T1 Heterozygous R1R2 L2L1 Practice with features (characteristics) and traits Match the feature provided with a possible trait (or variation) of that feature.
