Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If two

heterozygous individuals with polka-dot tails mate, what's the probability of the phenotype and genotype combinations of the offspring? A. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (75 percent Pp; 25 percent pp) B. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail C. 25 percent chance of a polka-dot tail and 75 percent chance of a solid colored tail D. 50 percent chance of a polka-dot tail and 50 percent chance of a solid colored tail

The correct answer is B. This question relates to using a punnet square to determine the genotypes of the offspring. Two heterozygous parents expressing a polka-dot tale must have genotype Pp each. 

Using a punnet square, this will produce 4 possible genotypes in equal probability:
PP - polka dot
Pp - polka dot
Pp - polka dot
pp - solid tale

Therefore there is a 75% change of getting polka dots in the offspring, and a 25% chance of solid tale.

A. is an incorrect answer because only 50% of offspring will be type Pp, another 25% will be expressing double dominant alleles for P as PP, which will still express polka dots.

Effectus [21]

Answer: D. Digestion increases as the volume of the enzyme increases.

Explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.
