The Basics of Genetics Vocabulary
Genetics is the scientific study of genes, how they are inherited, and how they influence the physical and behavioral traits of living things. Understanding genetic vocabulary is essential for explaining the concepts related to genetics. The following are some of the key terms and definitions used in genetics:
Gene
A gene is a segment of DNA that contains the instructions for making a protein or a functional RNA molecule. Each gene is located at a specific position on a chromosome and has a unique sequence of nucleotides. Genes determine an organism’s inherited traits and characteristics.
Allele
An allele is a variant form of a gene that arises by mutation and is located at the same position on homologous chromosomes. Alleles can be dominant or recessive, and they determine an organism’s phenotype.
Phenotype
Phenotype refers to the observable physical and behavioral traits of an organism, which are determined by the interaction of its genotype and the environment.
Genotype
Genotype refers to the genetic makeup of an organism, which is determined by the combination of alleles inherited from its parents and the interaction of these alleles.
Homozygous
Homozygous refers to an individual having two identical alleles for a particular gene, which may be either dominant or recessive.
Heterozygous
Heterozygous refers to an individual having two different alleles for a particular gene, which may be either dominant or recessive.
Dominant
Dominant refers to an allele that is expressed in an organism’s phenotype when present in either one or both copies. Dominant alleles mask the expression of recessive alleles.
Recessive
Recessive refers to an allele that is expressed in an organism’s phenotype only when present in two copies. Recessive alleles are masked by dominant alleles.
Punnett Square
A Punnett square is a diagram that is used to predict the probability of offspring inheriting specific traits from their parents based on the known genotypes of the parents.
