Frequency of allele a1 is 75%, p=0.75
Frequency of allele a2 is 25%, q=0.25
 If a population is in Hardy-Weinberg equilibrium then:
p2+2pq+q2=1
<span>p2  is the frequency of genotype a1a1 (homozygous),</span>
2pq is the frequency of genotype a1a2 (heterozygous),
q2 is the frequency of genotype a2a2
<span>The proportion of individuals with genotype a1a2 is then 2*0.75*0.25=0.375 (37.5%).</span>

What is the force of an object that needs a force 4500N to accelerate it at a rate of 5 m/s
babunello [35]

Answer:

The question is somehow not correct, it suppose to be what is the MASS of an object that needs a force 4500N to accelerate it at a rate of 5 m/s as gotten from another website.

The correct answer is 900kg.

Explanation:

To get the mass of the object use the formula

F=Ma

Where F is force

M is mass

a is acceleration.

F= 4500, M=? a=5m/s

4500= M× 5

M=4500/5

M=900kg

Mass is in kg
