Volcanoes and tectonic plates enrich land formation. When a volcanic eruption occurs, materials are brought to the surface that results in the formation of new islands. The actions of converging tectonic plates have created the most beautiful landforms and oceanic trenches. Also, eruptions better the soil quality in a given location. The mineral deposits emitted during an eruption is absorbed by the soil and becomes a lifelong source of nutrition.
Albinism is a recessive trait. A man and woman who both have normal pigmentation have one child out of three who has albinism (without melanin pigmentation). The genotypes of this child's parents: (C) Both parents must be heterozygous.
Albinism is an autosomal and not a sex-linked recessive trait.
Only homozygous recessive (aa) offspring will be albino, both homozygous dominant (AA) and heterozygous dominant (Aa) offspring will possess the normal phenotype.
Since it is given that both the father and the mother have normal pigmentation, thus they must both have the genotype Aa.
From the Punnett square it can be observed that a cross between the parents would result in the creation of three offspring with the normal genotype (one with AA and two with Aa) and one offspring with the genotype aa (albino).
