Question

1. if B us for dark blue feathers and b is for light blue feathers, what is the genotype for a medium blue parakeet

bb

BB

Bb

bB

2. which illustrates the concept of incomplete dominance in genetics?

a red flower and a white flower produce offspring that are pink

a black cow and a white cow produce offspring with patches of both black and white fur

a tall plant and a short plant produces no offspring that are medium height

a red flower and a white flower produce offspring that are all red

3. which best describes co-dominance in genetics

Both alleles in a heterozygous organism contribute equally and visibly to the organism's phenotype

one allele completely masks the effect of another allele

the phenotype of the homozygous organism is a combination of two recessive alleles from the heterozygous parent organisms.

the phenotype of the heterozygous organism is a blend of the phenotype of the two homozygous parent organisms

4. which is an example of co-dominance in genetics

a tall plant and a short plant produces offspring of a medium height

a black chicken and a white chicken produce offspring with both black and white feathers

a red flower and a white flower produce offspring that are all pink

a blue eyed parent and a brown eyed parent produce offspring either blue or brown eyes, but not a mix of both

Here are the answers to your questions:

1. **The genotype for a medium blue parakeet** is **Bb**. This is because the medium blue color likely results from one allele for dark blue (B) and one recessive allele for light blue (b), hence the heterozygous genotype Bb.

2. **The concept of incomplete dominance in genetics** is illustrated by **a red flower and a white flower produce offspring that are pink**. Incomplete dominance occurs when the heterozygous phenotype is a blending of the two homozygous phenotypes.

3. **The best description of co-dominance in genetics** is **Both alleles in a heterozygous organism contribute equally and visibly to the organism's phenotype**. Co-dominance results in both traits being expressed at the same time in the phenotype.

4. **An example of co-dominance in genetics** is **a black chicken and a white chicken produce offspring with both black and white feathers**. In this case, both phenotypes are expressed simultaneously and distinctly in the offspring.
