What is a gene?

A gene is a specific sequence of DNA that contains the instructions for producing a specific protein or RNA molecule, which in turn carries out a particular function in an organism. Genes are the basic units of heredity and are passed down from parents to offspring, playing a crucial role in determining an individual's traits and characteristics.

What is DNA?

DNA, or deoxyribonucleic acid, is a molecule that contains the genetic instructions for the development, functioning, growth, and reproduction of all living organisms. It consists of two long strands that coil around each other to form a double helix, with segments called genes that encode specific traits or characteristics. DNA is found in the cells of all living organisms and serves as the blueprint for the unique characteristics of each individual.

What is a chromosome?

A chromosome is a thread-like structure composed of DNA and protein found in the nucleus of a cell. It carries genetic information in the form of genes and plays a crucial role in the heredity and reproduction of organisms. Chromosomes are key components in the process of cell division, serving as the vehicle for transmission of genetic material from parent to offspring.

What is a genotype?

A genotype refers to the genetic makeup of an organism, specifically the combination of alleles that an individual inherits from its parents for a particular trait or traits. It represents the full set of genes that an organism carries in its DNA, influencing its physical characteristics and potential phenotypic traits.

What is a phenotype?

A phenotype is the observable physical characteristics or traits of an organism, resulting from the interaction of its genotype (genetic makeup) with the environment. These traits can include features such as eye color, height, and behavior, and they are the visible manifestations of the genetic information encoded in an organism's DNA.

What is a dominant trait?

A dominant trait is a genetic characteristic that is expressed in an individual when only one copy of the gene responsible for that trait is present in their genetic makeup. It will override the expression of a recessive trait when both dominant and recessive alleles are present in an individual's genotype for that specific trait.

What is a recessive trait?

A recessive trait is a genetic trait that is only expressed when an individual has two copies of the recessive allele. In contrast to dominant traits, recessive traits are masked by dominant alleles in heterozygous individuals. Examples of recessive traits include blue eye color and certain genetic disorders like cystic fibrosis.

What is a Punnett square?

A Punnett square is a diagram used in genetics to predict the possible genotypes of offspring from a specific genetic cross between two parents. It helps show the different combinations of alleles that can result from the parents' genetic makeup, allowing scientists to understand the likelihood of certain traits being passed on to the next generation.

What is genetic variation?

Genetic variation refers to differences in the genetic makeup of individuals within a species. It arises due to mutations, genetic recombination, and other genetic processes, resulting in diverse traits and characteristics. This variation is crucial for evolution and adaptation, allowing populations to better respond to environmental changes and ensuring the survival of a species.

What is genetic engineering?

Genetic engineering is a scientific process in which the DNA of an organism is altered or manipulated in order to introduce new traits or characteristics. This can be done by inserting genes from another organism, removing or modifying existing genes, or changing the expression of certain genes. Genetic engineering is used in various fields such as agriculture, medicine, and biotechnology to improve the characteristics of organisms for specific purposes.
