Revival, since the last post was a month ago:

In humans, curly hair is homozygous dominant, and straight hair is homozygous recessive. Being heterozygous results in wavy hair. Also, attached earlobes are recessive to unattached earlobes. Jane has curly hair and unattached earlobes. Her father had attached earlobes. Jane marries Harry, who has straight hair and attached earlobes.

1. What percentage of their children will have curly, wavy, and straight hair?
2. What is the chance that each of their children will have attached earlobes?
3. If Jane and Harry's daughter, Loreta, marries someone with the same hair as her, what will be the phenotypic ratio for hair in Loreta's children?
"Blessed are you when people insult you and persecute you, and falsely say all kinds of evil against you because of Me. Rejoice and be glad, for your reward in heaven is great; for in the same way they persecuted the prophets who were before you." Matthew 5:11-12

I have no regrets.

Dang, it's been a while since I've done this. Pretty sure these aren't right but...
1. 100% wavy, 0% straight, 0% curly
2. 50%
3. 1:2:1 (1 straight : 2 wavy : 1 curly)
