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.
If you have any further questions or need clarification, feel free to ask!
