For a dihybrid cross Bb x Bb, what is the genotype ratio of BB:Bb:bb?

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?

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)
