Thank you! Just something I noticed, at 4:18, for a recessive lethal allele, the phenotypic ratio is 1 not 2:1. That's because if the homozygous recessive dies out, then all the progeny will show the dominant phenotype. The genotype, however, is 2:1. A 2:1 phenotypic ratio indicates a homozygous dominant lethal allele following the same style of logic.
Ragul Natarajan the phenotypes are AA-agouti(1) and Aa-yellow(2), so 2:1 is the phenotypic and the genotypic ratio after accounting for the lethality of aa(1).
Chegg? R u interested in biology? Microbiology? Chemist? Transgene? Aerosol spray for gene maturity or aerosol spray for types of genes and embryo gene which can change into other genes? R u familiar with these topics?

Thank you, please point to the part you are talking about. This way we can follow more
EXACTLY DUDE
Finally the chegg
Thank you so much ☺
Does asthma count as a conditional lethal allele?
Thanks this really helped me!

very nice explanation but need to improve a lot
🙏✨💕
why do you say heterozygous so weird....
She cute I wonder if she’s currently single
It's little bit boring not like khanacdemy which is epic
Thank you ☺️💖
