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

Описание: 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!)...
