7.   Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If
Oksi-84 [34.3K]

Hi!

The correct answer would be A.

<h3>Explanation:</h3>

As the allele P for polka dot is dominant to the allele p for solid color, it would yield a Polka dot tail in the individual in the presence of just one allele of P, while masking the effect of p for solid color.

So the possible genotypes and phenotypes would be as follows:

  1. PP (Polka dot tail)
  2. Pp (Polka dot tail)
  3. pP (Polka dot tail)
  4. pp (Solid color tail)

Following a cross by two heterozygous individuals, there would be 25 percent chance (1/4) of having the genotype pp , 25 percent (1/4) chance of having the genotype PP and 50 percent (2/4) chance of having the genotype Pp.

But the phenotype yielded by Pp and PP offspring would be polka dots, so there is a 75 percent (3/4) chance of having polka dot offspring, and 25 percent chance of having solid colored tail offspring.

<h3>Hope this helps!</h3>

Which of the following would lead to an increase in species biodiversity in Florida?
antiseptic1488 [7]

Answer: D

Explanation:

Ensuring that they don't lose their habitat and protecting them is key. Not adding in other invasive species or overexploitation. Conserving would cut the pollution (and if done globally it would cut back global warming). So if we protect the current species more will come or the current will evolve and be able to reproduce.
