Yr 10 Genetics

Segment of a DNA molecule with a coded set of instructions in its base sequence for a specific protein product; when expressed, may determine the characteristics of an organism

• Genes
• Chromosome
• Autosome
• Nucleus

Tiny thread-like structures inside the nucleus of a cell. Chromosomes contain the DNA that carries genetic information.

• Chromosomes
• Gene
• Autosome
• Protin

A process that results in the production of new cells

• Cell division
• Telomeres

Cell division process that results in new genetically identical cells with the same number of chromosomes as the original cell

• Mitosis
• Meiosis
• Cytometry
• Fusion

Cell division process that results in new cells with half the number of chromosomes of the original cell

• Meiosis
• Mitosis
• Cytometry
• Fusion

Reproductive or sex cells such as sperm or ova

• Gametes
• Autosomes
• Somatic cells
• Homologues

Penetration of the ovum by a sperm

• Fertilization
• Fusion
• Gametes
• Autosomes

Cells of the body that are not sex cells

• Somatic cells
• Gametes
• Autosomes
• Homologues

Genetic instructions (contained in DNA) inherited from parents at a particular gene locus

• Genotype
• Phenotype
• Genetics
• Traits

Characteristics that result from the expression of an organism’s genotype. Depends on both the genotype and the environment.
