Tips for Working with Multiple Alleles!

What are multiple alleles? Spoiler: multiple alleles aren't special - you work problems (like Punnett squares) with multiple alleles the same way you'd work them for a gene with just two alleles. You just get more possibilities for genotypes and phenotypes! #MultipleAlleles #ABObloodgroup In this video, we look at three common issues students often run into with multiple alleles, so that you can avoid them! 00:00 Intro 00:20 NOTATION: multiple alleles are often written with a superscript, but we can also use superscript to label alleles in other scenarios - always read your question carefully! 01:02 The ABO blood group has three alleles, represented by the letter I with superscript; A and B are codominant, and both dominant over O. 02:14 GENOTYPES AND PLOIDY: you only get as many alleles as your ploidy allows! regardless of the number of alleles in your population, you only get two alleles in a diploid genotype (it could be two copies of the same allele, or two different alleles). 02:55 MULTIPLE ALLELES ARE COMMON: just because Mendel didn't want to study them doesn't mean they aren't everywhere :) 03:30 RECAP! Remember, ABO is the name of the group, it's not a genotype! New videos are always on the way - subscribe so you don't miss any of my biology tips :) Connect with me!
