Please help me!! what is the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy?
1 answer:
Answer:
3/16
Explanation:
This question involves two genes coding for pea shape and pea color. The alleles for yellow color (Y) and round seeds (R) are dominant over the alleles for green color (y) and wrinkled seeds (r).
In this cross between two heterozygotes: RrYy × RrYy, the following allele combinations are produced in the gamete of each parent: RY, Ry, rY and ry. Using these gametes in a punnet square (see attached image), the following offsprings are produced:
9/16 of Round, yellow offsprings (R_Y_)
3/16 of Round, green offsprings (R_yy)
3/16 of Wrinkled, yellow offsprings (rrY_)
1/16 of wrinkled, yellow offsprings (rryy)
Hence, the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy is 3/16.

Answer:
Option C
Explanation:
Please see the attached image for the panama canal
Solution
Shrimps are the species that live in the bottommost areas of any water body i.e the bottom of the river or at the base of an ocean floor. Some of them are in habit of hiding themselves into the sand, mud, and rock along the sea shore.
In the image, the region A1 and B1 is the region closest to the ocean surface and as stated earlier some species of shrimps live close of sea/ocean surface. Thus, A1 and B1 regions will have shrimp hybrids.
Hence, option C is correct
