Answer:
Option C
Explanation:
Let the allele for long fin trait be "L" and the allele for short fin trait be "l"
Given L is dominant over l
If he crosses a long fish and short fin to produce three fourth long fins and one fourth short fins, it is not confirmed that the long fin species are homozygous as represented in the cross below
Ll * Ll
LL, Ll. Ll, ll
The two parent species are long (but not homozygous). Hence, option A is incorrect
However, if this test cross is carried out several times, the recessive trait may disappear thereby producing only homozygous long finned species.
Hence, option C is correct

Explanation:
Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.
