Complete a cross between two organisms that are both heterozygous for black fur (bb which is dominant over white fur. use a punnett square to evaluate the possible genotypes. (3 points)
1. list all the genotypes from your punnett square for the offspring.
2. determine & list the phenotypes that can be produced in the offspring.
3. determine the probability of producing offspring with the bb genotype.
(hint: remember the process when completing all punnett squares ~ key, cross, g and p results)

the answer is trees if i'm not mistaken

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.
