Answer:
C. Hypothesis
Explanation:
Hypothesis is a proposed explanation for a certain occurrence and when the explanation is conclusive, then it becomes a theory.
So, we have two heterozygotous parents, let's call then PL and pl.
if they had children, the children could have either polka-dot tails or not and either long eyelashes, or not, this gives us 4 groups ( so we can reject options A and D which only mention 2 types).
now, there is only one option to have a phenotype which corresponds to recessive allele: that both parents have the recessive allele. So the smallest group will be the one with solid tails and short eye-lashes,
the correct answer is
B. 9:3:3:1 ratio (9 polka-dot tails and long eyelashes, 3 polka-dot
tails and short eyelashes, 3 solid tails and short eyelashes, 1 solid
tail and short eyelash)
DNA is considered the building blocks of life.
