CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Most traits are determined by more than one gene. For example, skin color and height are determined by many genes. Some phenotypes however, are determined by a single gene. We will explore some of these single gene traits in the laboratory.

Detailed explanation-2: -Complex traits are believed to result from variation within multiple genes and their interaction with behavioral and environmental factors. Complex traits do not follow readily predictable patterns of inheritance.

Detailed explanation-3: -Single-gene traits include some of the most observable physical traits in humans, like eye color, widow’s peak hairline, earlobe type (attached versus detached), presence of freckles or dimples, or the ability to roll your tongue.

Detailed explanation-4: -Traits that are determined by a single gene are of five main types: Y-linked, X-linked dominant, X-linked recessive, autosomal dominant, and autosomal recessive.

Detailed explanation-5: -Parents pass on traits or characteristics, such as eye colour and blood type, to their children through their genes. Some health conditions and diseases can be passed on genetically too. Sometimes, one characteristic has many different forms. For example, blood type can be A, B, AB or O.
