When Mom's DNA Calls the Shots: Genetic Maternal Effects

When do mom's genes override yours? When it's a genetic maternal effect! In this video, we'll see how the maternal genotype can determine an offspring's phenotype, regardless of what the offspring's own alleles say. We'll use snail shell coiling as an example of genetic maternal effect to see how maternal effect genes shape an offspring's phenotype early in development. And we'll briefly highlight how genetic maternal effect is different from cytoplasmic inheritance (even though mom is definitely important in that one, too!)... #geneticmaternaleffect #maternaleffect #snailshellcoiling 00:00 Intro 00:13 What is genetic maternal effect? 00:46 Maternal effect genes 01:46 Example of genetic maternal effect: snail shell coiling (dextral or sinistral) 05:14 Genetic maternal effect vs cytoplasmic inheritance Related videos: Genotype vs phenotype:    • Genotype and Phenotype Explained! With Exa...   Why are some alleles dominant or recessive?:    • Why Are Some Alleles Dominant or Recessive?   New videos are always on the way - subscribe so you don't miss any of my biology tips :) Connect with me!
