Explanation:
Aphotic zone of a body of water refers to the part where almost no sunlight. With this condition of water, marine life is limited to species who does not light for survival. The aphotic area also is the basin of the dead organism that submerges from the photic part. Temperatures at these areas are also low
<h2>Answer:</h2>
As in a given cross two genes control the height and flower color. Tall height (T) is dominant over the short height (t) and yellow flowers (Y) are dominant over the white flower (y).
When the tall yellow flowered mated with short white flowers, the genotype of the plants can be;
TTYY × ttyy or It can be TtYy × ttyy or TTYy × ttyy or TtYY × ttyy
All of these birds share a common ancestor
Hope i helped :3
Admitting that the "a" is a capital A for normal pigmentation and "d" is a capital D for dimpled chin, meaning that these are the dominant traits, the fraction expected to be albino with a non-dimpled chin is of 1/16.
When two heterozygous are crossed and two characteristics are being analysed, the offspring quantity that will possess the two recessive traits can be represented by 1/16. This is easily confirmed when a Punnett square is made. Considering that both parents were heterozygous, on both sides of the crossing in the Punnett square, you would have the following alleles' combination: AD, Ad, aD, and ad. The offspring that would be homozygous recessive (aadd) would correspond to only 1/16.
