What is the answer with explaining

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.

chordata is the answer

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
