Answer:
A. If neither parent expresses the trait, but the offspring does, both parents must be heterozygous for the trait.
Explanation:
If neither parents express the trait is because they are heterozygous and the dominant allele is being expressed over the recessive trait. When parents cross they have 25% of having an offspring that expresses the recessive trait, this means the offspring is a recessive homozygous. In the attached example 25% or 1/4 will have a short stem.
Answer:
All the offsprings would be heterozygous purple colored flower
Explanation:
Given
Purple color flower is dominant over white color flower
Let the allele for purple color of flower be represented by "P"
and the allele for white color flower be represented by "p"
A pea plant that is homozygous purple-flowered is crossed with a pea plant that is white-flowered.
Genotype of homozygous purple-flower is "PP"
and Genotype of homozygous white-flower is "pp"
Cross between PP and pp produce the following offspring
PP * pp
Pp, Pp , Pp , Pp
All the offsprings would be heterozygous purple colored flower
Answer:
Workers worked longer hours.
Explanation:
