Magine you are trying to determine the phenotypic ratio of hair color. Brown (B) hair color is the dominant trait and blonde (b) hair color is the recessive trait. What is the phenotypic ratio if one parent is heterozygous and the other parent is homozygous recessive for this trait? Group of answer choices 3:1 (brown:blonde) 3:1 (blonde:brown) 1:1 (brown:blonde)

1:1 (brown:blonde)

Explanation:

Brown hair color (B) is dominant over blonde hair color (b).

Heterozygous parent will have the genotype Bb

Homozygous recessive parent will have the genotype bb.

Crossing hetezygous parent with homozygous recessive parent:

Bb   x   bb

Progeny: Bb, Bb, bb, and bb.

2 Bb brown hair

2 bb blonde hair

Phenotypic ratio = 1:1 (brown:blonde)

The correct answer is  1:1 (brown:blonde).

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?
