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

Models of both atmospheric and oceanic circulation show predictable patterns of air and water movement across the globe. The
marusya05 [52]

Coriolis effect is the phenomenon that most directly causes these atmospheric and oceanic circulation patterns.

<h3>What is Coriolis effect?</h3>

This is defined as an apparent deflection of the path of an object that moves within a rotating coordinate system.

Atmospheric and oceanic circulation patterns aride from deflection of the direction of air and water currents moving towards or away from the poles.
