Answer:
Bottom line: The planets in our solar system orbit (revolve) around the sun, and the sun orbits (revolves) around the center of the Milky Way galaxy. We take about 225-250 million years to revolve once around the galaxy's center. This length of time is called a cosmic year.
Explanation:
<u>The</u><u> potential genotypes</u><u> for newborns with brown eyes are</u><u> BB and Bb</u><u>, whereas the potential genotype for newborns with blue eyes is bb.</u>
- According to the information provided above, b = allele for blue eyes is recessive while B = allele for brown eyes is dominant.
- A recessive allele is one that cannot express itself in the presence of a dominant allele, while a dominant allele conceals the effect of a recessive allele.
- A dominant allele expresses itself in the presence of a recessive allele.
- While a dominant allele can express itself in both a homozygous and heterozygous state, a recessive allele can only do so.
- Therefore, newborns with brown eyes will have two genotype options: BB and Bb, whereas those with blue eyes will only have one.
