Can two people with brown eyes have a blue eyed baby
Elena L [17]

Answer:

Yes

Explanation:

Each person has two alleles (forms of a gene) for a characteristic. We can represent them using letters.

Dominant trait are written as capitals. If a dominant allele is present in someone's genotype, the dominant trait will show.

The recessive trait only shows if a person has two recessive alleles.

Brown eyes is a dominant trait, and blue eyes is a recessive trait.

B = dominant brown eyes

b = recessive blue eyes

If someone has <u>brown</u> eyes, their genotype can be:

BB

Bb

If someone has blue eyes, their genotype is:

bb

The baby's genotype must be bb because it has blue eyes. <u>The baby gets one allele from each parent</u>.

See the photo for Punnett square. If the parents are both Bb, then they could each give the b allele, resulting in a blue-eyed baby.

a car has a foward acceleration how would the acceleration of the car be dofferent if it had more mass
Sergeu [11.5K]

Apply Newton's second law of motion to the car:

F = ma

F is the driving force moving the car, m is the car's mass, and a is the car's acceleration.

Assuming we apply the same F to another more massive car, it would move with a smaller acceleration.

If a boulder has a mass of 50 kg and a potential energy of 490 j what is the height of the boulder
Mkey [24]
Potential energy = mass x g x height.
height = potential energy/mass x g
acceleration due to gravity on earth is 9.8 m/s
filling in your variables gives us:
490/50 x 9.8 = 1 meter
