Its hard to explain but i will do my best now not to insult anyone but a long long time ago people would produce heirs with their own kind because they had no way of transportation to get to a different area their fore meet people of a different race.......big idea is races are losing their genes because we have a wider variety of people so the newest generation of children are not just Spanish or asian or dutch or any simple race their a huge mix of races and no one is a specific color (if you will) will be darker or paler. hope this helps you understand a bit more

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).
