<span>The theory of Alkaline Vents theorizes that life originated deep under the sea around hydrothermal vents. This could be likely because these vents provide plentiful methane and ammonia. Critics, however, point out that high temperatures are not conducive to organic life.</span>

The genes R, E and D are independently assorting and control production of red pigment as follows (recessive alleles are not fun
Alona [7]

Answer:

1/8

Explanation:

An individual must have all three dominant alleles to be red, in homozygosis or heterozygosis (R_E_D_).

<u>The parental cross was:</u>

RREEDD x rreedd

F1: RrEeDd

<u>The test cross</u> is between the RrEeDd indiviudals and homozygous recessive rreedd.

The genes assort independently, so we can use Mendel's law of segregation to predict separately for each gene the proportion of the offspring that will have the dominant alleles.

<h3><u>Rr x rr</u></h3>

1/2 Rr

1/2 rr

<h3><u>Ee x ee</u></h3>

1/2 Ee

1/2 ee

<h3><u>Dd x dd</u></h3>

1/2 Dd

1/2 dd

Genes are independent, so the probability of having a R_E_D_ offpsring is calculated by multiplying the individual probabilities of having a dominant allele for each gene:

1/2 (Rr) × 1/2 (Ee) × 1/2 (Dd)= 1/8

Which of the following occurs during the interphase stage of the cell cycle? I. DNA is replicated. II. The cell divides. III. Th
Vladimir79 [104]

Out of the following choices given;

A) II only

B) I and III only

C) I, II, and III

D) I and II only

The answer is B. Cells spend most of their life cycle in the interphase stage.  It is during this stage that the cells prepare itself for mitosis. Interphase of a cell cycle is divided into the G1, S, and G2 stages. The DNA duplicates in the S phase while growth of the cell occurs in the G1 and G2 stages.
