Answer:
75%
Explanation:
The autosomal gene for baldness has two possible alleles: Hb (baldness) and Hn (nonbaldness).
A man and a woman, both heterozygous <em>HnHb,</em> have a son. Each parent produces gametes <em>Hn</em> or <em>Hb</em>.
The possible genotypes of their children, resulting from the combinations of those gametes, are:
In males, the Hb allele is dominant. Therefore, their son has a chance of 3/4 = 0.75 = 75% of having the Hb allele which determines baldness.
Answer:
Explanation:
This is called the equivalence point. That is the exact point during titration where the relative amounts of each substance in the chemical reaction of titration become well defined by the coefficients in the balanced chemical equation used for expressing the kinetics of reaction.
A titration is an experimental set up with a controlled acid-base neutralization reaction.it is used to determine the unknown concentration of an acid or a base.
Acids and bases neutralize each other, forming a salt and water. Basically, a strong acid-strong base neutralization gives a neutral solution with a pH of 7.
