a. unit factors in pairs
b. dominance/recessiveness
c. random segregation
d. law of independent assortment
we concluded that the traits we studied about fur color follow a chain of dominance through observing the outcomes of several different crosses.
For example, we observed that spotting is recessive to having no spots, since there were more offspring without spots than those with. (patterning gene)
Another easy observation was that white/albinism is recessive to black fur coat. This was evident way back in the Parent generation cross between Moofish and the albinos, since no albinos showed up. (black to white)
The third color we dealt with was agouti; an odd combination of gray and brown tints. At first, we had trouble identifying this color because we couldnt distinguish whether it was brown or gray. But after many crosses, we decided that agouti was dominant over black, which is dominant over white. Because allelels work in pairs, we decided, however that non-agouti has dominance of agouti.
Therefore, we established the following chain of dominance:
agoui> black> white
nonspotted> spotted
