Answer:
f(A1) = 0.9700, f(A2) = 0.0300
Explanation:
According to Hardy-Weinberg equilibrium equation:
p + q = 1
p² + 2pq + q² = 1
where,
p = frequency of dominant allele
q = frequency of recessive allele
p² = frequency of dominant homozygous genotype
2pq = frequency of heterozygous genotype
q² = frequency of recessive homozygous genotype
q² = 9/10000 = 0.0009
A2 = q
= √0.0009 = 0.03
A1 = p
= 1-q
= 1-0.03 = 0.97
Answer:
"My child sleeps between 11 and 12 hours a night."
Explanation:
Sleep is extremely important for the child as it is during sleep that complex neurophysiological processes occur that determine the production of substances eg growth hormone that stimulates the development of muscle mass, promotes bone stretching, decreased fat accumulation , improves physical performance and activates the immune system.
Sleep time may vary with age, personality and family dynamics. But in general, children from 1 to 3 years sleep between 12 and 14 hours daily, the afternoon sleep between 1 and 2 hours. Between 3 and 5 years is 11 to 12 hours daily. By age 4 most children no longer sleep during the day. From 6 to 12 years old, children are of school age and it is recommended that they sleep between 10 and 11 hours.
