<p>Allele = Different forms of a gene that can affect individual characteristics and disease risk. Gene = Units of hereditary information composed of DNA that help cells reproduce and manufacture life-sustaining proteins. Chromosome = Structures within the nucleus of a cell that carry genetic information Mitosis = Process of cell division that produces identical daughter cells for growth and repair.

Units of hereditary information composed of DNA that help cells reproduce and produce proteins.

A process where body cells duplicate themselves to grow and repair tissues, creating exact replicas.

The process of cellular division that produces gametes (sex cells) with half the number of chromosomes.

The fertilized egg formed when the ovum and sperm cell combine, containing 46 chromosomes.

Different forms of genes that influence characteristics and affect disease risk.

A gene that expresses its trait even when only one copy is present in the genotype (represented as 'Y').

A gene that expresses its trait only when two copies are present (homozygous, represented as 'yy').

Genetic condition where the mutated gene is carried on the X chromosome, often affecting males more.

Essential molecules made of amino acids for body structure and function.

The part of the genome that regulates gene expression by modifying DNA chemicals.

Chemical changes around DNA that influence gene expression without altering the DNA sequence itself.

The relationship between genetic inheritance and the environment provided for offspring, including passive, evocative, and active correlations.

A type of heredity-environment relationship where biological parents provide environments based on their traits.
