In guinea pigs, black fur (B) is dominant to brown (b) and short fur (S) is dominant to long (s). A heterozygous black, short-furred guinea pig (BbSs) males with a brown long-furred guinea pig.  The expected results are:  

In fruit flies, long wings (L) are dominant over short wings (II), and gray body (G) is dominant over black body (gg).  If a heterozygous long wing, black-body fly (Llgg) reproduces with a short wing, heterozygous gray-body fly (IIGg), what phenotypic ratio is expected among the offspring?  

The diploid number of chromosomes is found in somatic cells while the haploid number is found in gametes.

How many electrons are present in a stable or full energy level (shell) for hydrogen (H) and helium (He), the two lightest atoms.

Which is true when anaerobic fermentation occurs in human muscle cells and bacteria?

Two atoms can become more stable by:

Why is photosynthesis considered an an anabolic pathway?

The F2 (second filial) phenotypic ratio of monohybrid cross involving parents that are homozygous dominant and homozygous recessive is:

In a plant cell, molecules of chlorophyll are located in the membranes of:

Assume that an incompletely dominant gene controls the feather color in chickens so that BB produces black, BW produces a slate-gray color called blue, and WW produces asplashed-white.  A second gene on a separate chromosome controls comb shape, with the dominant gene R producing a rose comb and the recessive genes rr producing a single comb. A homozygous black, single comb-chicken is mated with a homozygous white, rose-comb chicken.  The offspring are the allowed to breed freely among themselves.  What proportion of their offspring (this would be the second filial (F2) generation) would have white feathers and single comb?
