A it depends on a chance event that changes the gene pool
Firstly, do you know what a phenotype is?
Answer:
We’ve come to use the word “skepticism,” in our society, most often, to express doubt in new or “far out” ideas. Originally, in ancient Greece, skepticism was the philosophy of questioning all claims, religious, ethical, scientific, or otherwise.
Explanation:
This is what I got from searching
Using a Punnett Square you can solve this. If two heterozygous individuals with polka-dot tails mate then both their genotype would be Pp. The Punnett square will then look like this:
P p
P PP Pp
p Pp pp
Now if you look at the square, you have the following genotype and phenotype combinations:
PP = 1 out of 4 = 25% : Homozygous polka-dot.
Pp = 2 out of 4 = 50%: Heterozygous polka-dot
pp = 1 out of 4 = 25% Homozygous solid color
With that the answer would then be A. <span>75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (25 percent PP; 50 percent Pp; 25 percent pp).</span>
