AI Thread Summary
The discussion centers on understanding how eye color inheritance works in relation to parental genetics. The original poster inquires about the potential eye color alleles they might pass on to their future children, noting the varied eye colors in their family. It is clarified that blue eyes are homozygous recessive (bb), while brown eyes can be either homozygous dominant (BB) or heterozygous (Bb). The eye color of a partner significantly influences the potential eye colors of offspring. Additionally, it is emphasized that eye color is a polygenic trait, making precise predictions difficult due to the involvement of multiple genes.

I have a question. My parents have green eyes, one sister has brown eyes, another has hazel eyes and the last sister & I have blue eyes. Given this information, how can I determine what eye color alleles I might pass on to my children?

No, I'm not trying to predict my childrens' eye color. I'm not even married yet.

Blue eyes are most certainly homozygous dominant (bb). Therefore it will depend on your significant other's eye color. If she has brown eyes then your offspring will probably have brown eyes (Bb).

Corrected your words. And eye color is actually a polygenic trait, so it's technically hard to predict.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
