In rabbits, gray hair(g) is dominant to white hair,(g),and black eyes(b) are dominant to red eyes (b).these two traits are independent of each other .in other words, female rabbit with the genotype ggbb may produce eggs with the alleles gb, bb, gb, or gb. to predict the probability of these sorts of crosses ,we will make a dihybrid punnet square

The question is incomplete. The rest of the question is :What are the phenotypes (descriptions) of rabbits that have the following genotypes:

Ggbb ggBB

ggbb GgBb

The phenotypes of the following genotypes will be :

Ggbb: Gray fur, red eyes

ggBB: White fur, black eyes

ggbb: White fur, red eyes

GgBb: Gray fur, black eyes

A dominant trait can be described as a trait that suppresses the effect of a recessive trait. A recessive trait can be described as a trait that gets masked by a dominant trait. For example, in the above scenario the gray hair allele is dominant over the whit hair allele and the black eye colour is dominant over red eye colour.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
