Genetics is the branch of biology that deals with the study of heredity and its biological process. It also involves the study of genes, genomes and the cell cycle.

Genetics is the science of heredity and how new life changes and varies in their characteristics. Sexual reproduction in humans involves 2 gametes; one male gamete, the sperm, and one female gamete, the egg. As was discussed in the cell division webpage the gametes are haploid (n).

Each gene's code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T) — in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.

Genetics methodologies provide powerful ways to investigate biological processes, and can ultimately reveal the underlying molecular mechanisms involved even when there is no knowledge at the outset of a study as to the mechanistic basis of a biological phenomenon.

A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).

A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).

We usually use a lower case letter to indicate recessiveness (b). Examples. A heterozygous calf has one red allele and one black allele (Bb). These animals are always black. This tells you that the black allele is dominant and the red allele is recessive because the black coloration is hiding the red.

Gene, allele, locus, site In the original terminology, still used by some population geneticists, genes occur in pairs on homologous chromosomes. In this terminology the four blood groups A, B, O and AB (defined in terms of agglutination reactions) are determined by three (allelic) genes: A, B and O.

Dominant alleles are represented with an UPPERCASE letter (B, T). Recessive alleles are represented with a LOWERCASE letter (b or t).

An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.

What Is Genetics? Genetics is the study of genes. Our genes carry information that gets passed from one generation to the next. For example, genes are why one child has blonde hair like their mother, while their sibling has brown hair like their father.

Genetics is the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work.
