Answer:
Alleles for albinism:
C (dominant)
c (recessive)
Genotypes:
- A: Cc
- B: Cc
- C: Cc
- D: Cc
- E: cc
- F: CC (expected genotype)
- G: CC
Explanation:
In humans, albinism is controlled by a single recessive allele 'c', whereas normal pigmentation of the skin is controlled by the normal allele 'C'. Moreover, a pedigree is a diagram that shows the inheritance pattern of a particular disease/disease through several generations. In a pedigree, a shaded circle (female) or a shaded square (male) indicates that the person expresses the disease/trait. On the other hand, an unfilled circle/square indicates that the person does not have the genetic trait. A carrier (heterozygous) individual can be represented by a half-shaded circle/square. In this pedigree, the genotypes of carrier and non-carriers individuals are represented by unfilled circles or squares; however, these genotypes can be deduced by determining the genotypes of their parents. For example, both A and B don't express the trait but they have a daughter (E individual) with albinism (cc genotype), thereby both A and B individuals need to be carriers (Cc genotype) for the trait.
Answer:
Glycolysis is actually a series of ten chemical reactions that requires the input of two ATP molecules. This input is used to generate four new ATP molecules, which means that glycolysis results in a net gain of two ATPs.

The answer is: A nerve block
A nerve block is a procedure of regional anesthesia, surgical or medical injections of substances, aimed at removing pain for a period of time, up to the final eradication of this pain, for therapeutic or diagnostic purposes.This procedure involves the local injection of anesthetic instead of pain. The anesthetic is usually directed to the nerve that serves the pain area.
