4. Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If t
lisov135 [29]

Answer:

The correct answer would be:

  • Genotype ratio: 1 (PP) : 2 (Pp) : 1 (pp)
  • Phenotypic ratio: 3 (polka-dot tails) : solid colored tail

The genotype of both parents is Pp (heterozygous).

Thus, both the parent would produce two types of gametes which are P and p.

The cross would result in the production of offspring with three types of genotype PP, Pp, and pp in 1:2:1.

Offspring with PP and Pp will have a polka-dotted tail as it is the dominant trait.

Thus, the phenotype ratio would be 3 (polka-dotted tail) : 1 (solid colored tail).

<h3>Answer:</h3>

B] Meters per second

<h3>Explanation:</h3>

  • Now the remaining options are <u>miles per hour</u> and <u>Meter per second.</u>

  • In comparison with both of these;

we know that metre per second is the SI unit of average speed and hence the answer is <u>meters</u><u> per </u><u>second</u>.
