Facial dimples and free earlobes are both considered dominant human traits. What are the expected phenotypes of the offspring of a female with dimples and free earlobes (DDFf) and a male with no dimples and attached earlobes (ddff)? Group of answer choices

Respuesta :

Answer: 50% with dimples and free earlobes and 50% with dimples and attached earlobes

Explanation:

Since both the facial dimples and free earlobes are considered to be dominant human traits, this implies that the expected phenotypes of the offspring with regards to the scenario given in the question would be 50% with dimples and free earlobes and also there will be 50% with dimples and a attached earlobes.

50% with dimples and free earlobes and 50% with dimples and attached earlobes.

  • Dominant and recessive traits exist when a trait has two different forms at the gene level.
  • The trait that first appears or is visibly expressed in the organism is called the dominant trait.
  • The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.

Since both the facial dimples and free earlobes are considered to be dominant human traits, this implies that the expected phenotypes of the offspring with regards to the scenario given in the question would be 50% with dimples and free earlobes and also there will be 50% with dimples and an attached earlobes.
