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.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
