Which one of the following statements about the cell cycle is correct?
faust18 [17]

Answer:

The correct answer is option C. "Most cells in the human body are in G0".

Explanation:

G0 is the phase of the cell cycle at which the cells are in a quiescent state. Basically, this is considered as a "normal" state for the cells, because at this point the cells are neither dividing nor preparing to divide. Most cells in the human body are in G0, because most cells in the body are fully differentiated, particularly adult neuronal cells.

Paul [167]

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858
