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.

The earth is capable of what?
Answer:
Natural selection is the application of pesticides.
Explanation:
Natural selection is a process which is non- random in which a trait increase or decrease in a population due to difference in the survival rate of a population that have that trait. So natural selection helps in the evolution of a population which is more adaptable.
Therefore when a pesticide is used against beetle many of the beetle die due to the pesticide but some beetles survived because they were having a gene that code for an enzyme that breaks down the toxin of pesticide which survived.
So nature selected those individuals who have genes that allow them to survive in changing and adverse conditions. So these selected individuals will reproduce and pass their genes to their offspring and increase in number.
Therefore by natural selection, more pesticide-resistant beetle will be produced and so more amount of pesticide should be needed to kill the beetles.
It happens slowly because it is something that happens over generations due to adaptive mutations. Environmental evolution is happening fast
