A widow's peak hairline (W) is dominant to straight hairline (w). Cross a heterozygous widow's
peak hairline person with a straight hairline person. What are the genotypic and phenotypic
ratios of their offspring

Respuesta :

Answer:

Use a punnett square! I'll attach an example.

Genotype - Genetic constitution of dominant and recessive traits inherited from parents. BB, Bb, & bb can be used to represent these.

Phenotype - Observable. If a dominant trait is present, it shows as the phenotype. For example, brown hair is dominant to blonde hair. A person with a BB or Bb genotype will have brown hair, but a person with a bb genotype will have blonde hair.

Statistically, they have a 50% chance of a child with a widow's peak, and a 50% chance of a child with a straight hairline.

The genotypic and phenotypic ratios of their offspring are 50% and 50% ratio of the child.

What are the heterozygous ?

The heterozygous are the condition where you have inherited different forms of a particular gene from each Β of your biological parents. By different shapes we generally mean that there are different parts of the gene where the sequence is different.

  1. Genotype - Genetic charter of dominant and recessive developments inherited from parents. BB, Bb, & bb may be used to symbolize these.
  2. Phenotype - Observable. If a dominant trait is present, it indicates because the phenotype. For example, brown hair is dominant to blonde hair. A individual with a BB or Bb genotype may have brown hair, however someone with a bb genotype may have blonde hair.
  3. Statistically, they've a 50% risk of a toddler with a widow's peak, and a 50% risk of a toddler with a instantly hairline.
