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.
Answer:
the force acting on the team mate is 1.19 kN.
Explanation:
given,
mass = 196 lbm
while tackling, the deceleration is from velocity 6.7 m/s to 0 m/s
time taken for deceleration = 0.5 sec
F = mass × acceleration
acceleration =
= -13.4 m/s²
1 lbs = 0.453 kg
196 lbs = 196 × 0.453 = 88.79 kg
F = 88.79 × 13.4
F = 1189.786 N = 1.19 kN
hence, the force acting on the team mate is 1.19 kN.
