Study Notes
Heredity Vocabulary
- Polygenic Inheritance: Involves multiple genes influencing a single trait, leading to a range of phenotypic expressions.
- Allele: Different forms of a gene that determine specific traits.
- Codominance: A genetic scenario where both alleles in a heterozygous genotype are fully and distinctly expressed in the phenotype.
- Autosomes: Non-sex chromosomes in humans, accounting for chromosome pairs 1 through 44.
- Recessive: An allele that is only phenotypically expressed when present in a homozygous form.
- Sex-Linked: Refers to genes located on the X chromosome, influencing traits often related to gender.
- Law of Independent Assortment: States that allele pairs separate independently during gamete formation, resulting in diverse genetic combinations.
- Karyotype: A visual representation of an individual's chromosomes, organized in homologous pairs.
- Protein: Essential macromolecules synthesized based on genetic information encoded in DNA.
- Heterozygous: Describes a genotype with two different alleles for a given gene inherited from each parent.
- Gene: A DNA sequence on a chromosome that encodes instructions for producing specific proteins.
- Linked Genes: Genes that tend to be inherited together due to their close proximity on the same chromosome.
- Dominant: Refers to an allele that can mask the effect of another allele when present in a heterozygous genotype.
- Phenotype: The observable traits or characteristics resulting from an organism's genotype.
- Multiple Alleles: Situations where more than two alleles exist for a single gene, allowing for complex inheritance patterns.
- Chromosome: Structures within cells that house genetic material, consisting of DNA tightly coiled around proteins.
- Epistasis: The interaction where one gene can suppress or modify the expression of another gene in polygenic traits.
- Law of Segregation: Each gamete receives only one chromosome from each homologous pair during meiosis.
- Homozygous: A genotype formed by inheriting identical alleles from both parents.
- DNA: The foundational macromolecule carrying genetic blueprints for an organism's development and functioning.
- Incomplete Dominance: A genetic expression pattern where the heterozygous phenotype is a blend of the two alleles.
- Genotype: The genetic makeup of an organism, represented by the specific alleles inherited.
- Sex Chromosomes: Chromosomes that determine an individual's biological sex, primarily X and Y chromosomes.
- Carrier: An individual who possesses a gene for a particular trait or genetic disorder but does not exhibit the trait or disorder.
- Law of Dominance: Some alleles can overshadow the effect of others, with dominant alleles prevailing in heterozygous conditions.
