The cellular structures that contain genetic information are called:
alleles
genes
chromosomes
heritable units
WTF alleles alt genes, genes carry genetic info, and so do chromosomes. I think this prof is not sure what answer he's looking for.
All of them except heritable units satisfy the question. I'm going to answer chromosomes, but any ideas if that fits the question best, or one of the other answers?
edit: actually I want to answer genes, but that's too obvious..
edit2:
Can some physical traits be dominant, while others are recessive?
only during a mutation
sometimes
no
yes
WTF kind of college class is this? I learned this shit in grade school...
