Title: modes of inheritance???
Post by: curry_bro on September 08, 2012, 12:59:14 pm

when refering to various modes of inheritance, is a question refering to:

1. complete dominance, incomplete dominance or codominance

or

2. autosomal dominant/recessive, X-linked dominant/recessive, Y-linked?????

im really confused.

Was there any backstory that enabled you to find whether the genotype was dominant/recessive etc?

I would say
1. complete dominance, incomplete dominance or codominance

Me too, just because they would only be referring to X-linked etc for humans only.
