Genetics
Gene- The basic physical and functional unit of heredity 
Punnett Square- It is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
Genotype- The genetic makeup of an organism
Heterozygous- Refers to having inherited different forms of a particular gene from each parent.
Genetic Diversity- The variation in the amount of genetic information within and among individuals of a population, a species, or a community.

Allele- Is a variant form of a gene

Diploid- Describes a cell that contains two copies of each chromosome.
Incomplete Dominance- Two copies of a gene for a particular trait, or alleles, combine so that neither dominates the other.
GMO- Genetically modified organism is any organism whose genetic material has been altered using genetic engineering technologies.
Recessive- Is the quality found in the relationship between two versions of a gene.
Codominance- It is a relationship between two version of a gene.
Homozygous- Having two identical alleles of a particular gene.
Variation- The difference in DNA among individuals or the differences between population.
Phenotype- The set of observable traits characteristics of an individual resulting from the interaction of its genotype with the environment.
Heredity- The sum of all biological processes by which particular characteristics are transmitted from parents to offspring
Haploid- Describes a cell that contains a single set of chromosomes.
Sexual Reproduction- The production of new living organisms by combining genetic information from two individuals different types (sexes).
Sex Cells (gametes)- These are an organism's reproductive cells.
Meiosis- A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent.
Mutation- A change in a DNA sequence.
