Answer:
Xᵇ Xᴮ : tortoiseshell female;
Xᵇ Xᵇ : orange female;
Xᴮ Y: black male;
Xᵇ Y: orange male.
Explanation:
The possible genotypes and phenotypes for coat color in cats is:
<u>Females</u>
- XᵇXᵇ: orange
- XᴮXᴮ: black
- XᴮXᵇ: tortoiseshell
<u>Males</u>
<u>Cross of an orange male and a tortoiseshell female</u>
XᵇY x XᴮXᵇ
The male produces the gametes Xᵇ and Y; the female produces the gametes Xᴮ and Xᵇ.
<u>The expected offspring resulting from the combination of those gametes is:</u>
- Xᵇ Xᴮ : tortoiseshell female
- Xᵇ Xᵇ : orange female
- Xᴮ Y: black male
- Xᵇ Y: orange male

Answer:C
Explanation:
During termination of transcription a section of DNA contains about 20 basepair GC nucleotides. This GC rich sequence that marks the end of a gene during transcription.
In the Rho-independent transcription termination mechanisms, the formation hairpin rich in GC nucleotides causes RNA polymerase to stall,
It is difficult for RNA polymerase can to work pass through GC rich hairpin, because GC basepair is made of 3 hydrogen bonds.
This causes the RNA polymerase to stall
