The case of golden labs in which a mutation in a gene for the pigment transport protein results in a lack of pigment (the golden color) instead of the brown or black the results from the actual pigment genes, is an example of...
Select one:

d. altered methylation
a. What is the Raly gene? What does it encode? How does it relate to the lethality of Ay?
b. A heterozygous mouse AAy does not produce enough pigment and it is yellow. Homozygous individuals die during development, but AAy heterozygous do not. Why? You may use any graphic aid to explain this, if necessary. This means that you may use a Punnett square or a forking segregation diagram, or computations with fractions.
c. Explain why there is a non-Mendelian 2:1 yellow/agouti phenotypic ratio in this cross.
