Ou are given two true-breeding groups of rabbits. The first group has floppy ears and white fur. The second group has straight ears and black fur. When you perform a cross of these two groups to obtain a F1 generation you see that all of your rabbits have floppy ears and gray fur. If you knew that each of these traits was determined by a single gene and underwent independent assortment, then you expect to see that 75% of your F2 generation rabbits have ears and of your rabbits have black fur.

you expect to see that 75% of your F2 generation rabbits have floppy ears and 25% of your rabbits have black fur.

Explanation:

Available data:

Having this information we can infer that floppy years, expressed by F allele, might be dominant over straight ears, expressed by f allele. And that the fur color is affected by incomplete dominance, being B the allele expressing black color, b the allele expressing white color and Bb the genotype for grey color.

Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring 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.

    elongation: in which 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.

    termination: in which 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.
