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
They are saying that every theory can eventually be changed a bit due to further research. It does not mean the theory is bad, just that it can become better.
