Answer:
the answer is this
Explanation:
In these oceans, extremely small dead organic matter - classified as plankton - falls to the floor of the ocean It is this sediment on the ocean floor that then forms oil over many years. The energy in oil initially comes from the Sun, and is energy from sunlight that is trapped in chemical form by dead plankton
<span>Stabilizing selection operates when individuals within a population of average body size have more offspring than those of large or small body size. this is the worlds way of stabilizing the population to a safe average.</span>
Answer:
See the answer below
Explanation:
From the illustration, the yellow color trait is dominant over the green trait.
<em>Assuming that yellow seededness is represented by the allele Y and green seededness by the alleles y. Y is dominant over y, hence a yellow seeded plant would be either YY or Yy while a green seeded plant would be yy.</em>
For a cross between a yellow seeded plant and a green seeded plant to yield all yellow seeded offspring, it means that the parents are YY and yy.
(yellow)YY x (green) yy
F1 progeny: All Yy (yellow)
Now, Yy is crossed with green-seeded plant, yy.
Yy x yy
Yy Yy yy yy
Hypothesized Genotypic ratio
Yy = 1/2
yy = 1/2
Hypothesized Phenotypic ratio
Yellow seeded = 1/2
green seeded = 1/2
