You are interested in two traits in rabbits, each of which is controlled by a separate gene with two alleles:

a) coat color (brown, b, is completely dominant to white,

b) and tail (tailed, t, is completely dominant to tail-less,

c) you cross a brown, tailed rabbit that is heterozygous at both loci with a white, tail-less rabbit and produce a large number of offspring.

among the offspring you find only two phenotypes in equal proportions: brown, tailed and white, tail-less.

the scenario here with the brown tailed rabbit RrTt

The white tailess rabbit is rt.

Crossing both yields the below offsprings possibilities;

For colour: Rr or rr

For tail: Tt or tt

That means they would produce equal numbers of Brown tailed & white tailess rabbits.

Explanation:

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
