What does the illustrated process show about the differences in patterns of embryology among kinds of animals?

Eeny, Meeny, Miny..Domino?

OK, some alleles are dominant and show up...some allelesshow a mixture of the combination. What happened here with this domino chicken? Both alleles are expressed!

Dihybrid Cross

Give me the phenotypic ratio of the following Dihybrid cross.

Tall-dominant
Dwarf-recessive
Purple Flowers-dominant
White-recessive

Cross a plant that is heterozygous for both traits with a plant that is homozygous tall with white flowers.

Is Dominant Dominant all of the time??

We have been talking about dominant and recessive genes. The dominant allele is expressed (shows) in the presence of a recessive allele. How can a white FOur-o'clock and a violet Four-o'clock produce a purple Four-o'clock when crossed?

What happened to my hair?

What is the name for pattern baldness? Explain, using genetics, why more men experience male pattern baldness than women.
Can you list any other genetic traits or disorders that work the same way as pattern baldness?
