Hence, option A is correct
The virus will be transmitted through the birds feces and could be spread to other animals and humans.
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
Answer: No
Explanation: It is beneficial if the animals that are disadvantageous doesn't reproduce so it doesn't discredit natural selection. The traits in which variation is occured are more suitable for organism to live and reproduce in the environment are preserved and are passed from generation to generation.
However, natural selection effects limited number of progeny.
