Sickle cell disease (SCD) is caused by a recessive version of the hemoglobin gene. In the US, SCD occurs in about 0.2% of the ne
ludmilkaskok [199]

Answer:

Number of babies with dominant hemoglobin genotype will be 9120

Explanation:

Given -

0.2% of babies have SCD which means they have recessive version of hemoglobin

Let the recessive version of hemoglobin be represented by "h" and normal version of hemoglobin be represented by "H"

Babies having SCD will have genotype "hh" i.e homozygous recessive.

As per Hardy Weinberg's equation -

q^2= 0.002

Thus, frequency of allele for recessive version of hemoglobin (h) is

\sqrt{q^2} \\= \sqrt{0.002} \\= 0.045\\

Frequency of allele for normal version of hemoglobin (H) is

1-0.045\\= 0.955

Thus, Frequency  of population with normal version of hemoglobin i.e HH is equal to

p^{2}

= 0.955^2\\= 0.912

hence, number of babies with dominant hemoglobin genotype will be

0.912 * 10000

= 9120

Which of the following molecules provides the energy to make glucose through photosynthesis?
MAXImum [283]
During photosynthesis, plants take in water and carbon dioxide and absorb light energy. Plants use the light energy captured by chlorophyll to help form glucose molecules. Glucose molecules store energy.To use this energy,a plant cell needs its mitochondria to break down the glucose.This process of breaking down food molecules to get energy is called cellular respiration.During cellular respiration,cells use oxygen to break down food molecules.Like all cells, plant cells then use the energy from food to do work
