SUMMARY

The discussion centers on determining the eye color alleles one might pass to children based on parental eye colors. It is established that blue eyes are homozygous recessive (bb), while brown eyes are typically heterozygous (Bb). The polygenic nature of eye color complicates predictions, as the offspring's eye color will depend significantly on the eye color of the partner. The presence of multiple eye colors in the family indicates a complex inheritance pattern.

PREREQUISITES
  • Understanding of basic genetics, specifically Mendelian inheritance
  • Knowledge of homozygous and heterozygous alleles
  • Familiarity with polygenic traits
  • Basic concepts of dominant and recessive traits
NEXT STEPS
  • Research the genetics of polygenic traits in humans
  • Learn about Mendelian inheritance patterns
  • Explore the implications of eye color genetics in offspring
  • Investigate genetic testing options for predicting hereditary traits
USEFUL FOR

Individuals interested in genetics, prospective parents, and anyone studying inheritance patterns in traits such as eye color.

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.
