As discussed previously, the ABO locus in humans has three alleles, where IAand IBare co-dominant and i is recessive to each. Su
Ivahew [28]

Answer:

Explanation:

using the formula p² + 2pq + 2pr + q²+ 2qr + r² = 1 where p is IA allele is 0.35 and q is IB allele is 0.15.

Thus, the expected frequency of people with type AB blood in this population will be (2pq) = 2 x 0.35 x 0.15 = 0.105

b. The expected frequency of people with type A blood will be p² + 2pr = where r is found using the formular p + q + r = 1 = 1 - (p+q) = 1 - (0.35+0.15) = 0.5

Thus, we have the expected frequency of people with type A blood to be     (0.35² + 2x0.35x0.5) = 0.4725.

c.    <u> p² + 2pr</u> + <u>2pq </u>+ <u>q² + 2qr</u> +<u> r²</u>

       AA AO      AB      BB BO     OO

         1850       180        635      2335

frequency of IA- p = (1850 + 180/2) / 5000 = 0.388

frequency of IB- q = (635 + 180/2) / 5000 = 0.145

frequency of i- r = 2335/ 5000 = 0.467.

since r² = 2335, r = √2335 = 48.32

using the formula p + q + r = 1

Use the balanced equation of a nitrogen cycle pathway below to support the conservation of matter and energy.
nadezda [96]
<h3><u>Answer and explanation</u>;</h3>
  • <u>According to the Law of conservation of mass; Mass cannot be created or destroyed in a chemical reaction.</u> The law of conservation of mass states that the total mass of substances taking part in a chemical reaction is conserved during the reaction. <u><em>For example in the equation;</em></u>
  • <u><em>N2 + 8 H --> 2 NH3 + H2</em></u>
  • <u><em>The number of hydrogen atoms and nitrogen atoms in the reactant side is equal to those on the product side.</em></u>
  • Additionally; <em><u>the law of conservation of energy states that the total energy of an isolated system remains constant, that is it can not be created or destroyed, rather, it can only be transformed or transferred from one form to another.</u></em>
