Patterns of Inheritance L10

These flashcards cover key concepts and terms related to patterns of inheritance, including mechanisms of sex determination, types of genetic traits, and examples of inheritance patterns.

Sex Chromosomes

Chromosomes that determine the sex of an individual, often designated as X and Y in humans.

X-linked traits

Traits that are associated with genes located on the X chromosome, often affecting males more than females.

Hemophilia A

A recessive X-linked blood clotting disease caused by a mutation in a clotting protein.

Morgan's Experiment

Research demonstrating a correlation between a genetic trait (eye color) and the inheritance of sex chromosomes in Drosophila.

Mendelian Inheritance

The pattern of inheritance that follows the laws established by Gregor Mendel, where alleles can be dominant or recessive.

Pleiotropy

The ability of a single gene to affect multiple traits or phenotypes.

Cystic Fibrosis (CF)

A genetic disorder caused by mutations affecting chloride ion transport, leading to multiple health issues such as thick mucus production.

Codominance

A form of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits equally.

Incomplete Dominance

A genetic scenario where the phenotype of heterozygotes is intermediate between the phenotypes of the homozygotes.

Environmental Sex Determination

A mechanism where the sex of an individual is determined by environmental factors, such as temperature in certain reptiles and fish.
