Homozygous having identical alleles for a single trait.
Heterozygous -Genes come in pairs, called alleles, and each pair is located in a specific position (or locus) on a chromosome
Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C.
Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene.
Autosome(s) Any chromosome not considered as a sex chromosome, or is not involved in sex determination. It occurs in pairs in somatic cells and singly in sex cells (gametes) Supplement
Sex chromosome An allosome is a chromosome that differs from an ordinary autosome in form, size, and behavior
Sex-linked A particularly important category of genetic linkage has to do with the X and Y sexchromosomes.
Deoxyribonucleic Acid (DNA) is a molecule that contains the instructions an organism needs to develop, live and reproduce
Ribonucleic Acid (RNA) A nucleic acid that is frequently single-stranded and folded onto itself, and composed of repeating nucleotide units of ribose sugar, phosphate group, and nitrogenous base.
Replication The process of duplicating or producing an exact copy of a polynucleotide strand such as DNA
Nitrogenous bases is simply a nitrogen-containing molecule that has the same chemical properties as a base
Nucleotide is one of the structural components, or building blocks, of DNA and RNA. A nucleotide consists of a base
