I need the choices provided to depict which is the better statement. <span />
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
Biomagnification is the term used to show the increasing concentrations of a substance as one moves up the food chain.
