Genetics and Evolution

The species is a biological classification comprising organisms that are related and share common characteristics and also are capable of breeding within the same individuals known as interbreeding. In biology, this biological species concept is vastly used and also related in the fields of study. In biology, there are more than 20 other different species […]

The inheritance of a trait (phenotype)that is decided by way of means of a gene positioned on one of the sex chromosomes is known as sex linked inheritance. In 1910, T.H Morgan described the roles played by chromosomes during heredity. The genes controlling frame characters positioned on X chromosomes are known as X-linked genes. The

Introduction The physical characteristics, that also are called physical/phenotypic traits within the field of genetic science, that are determined by the genes presence t on the sex chromosomes (allosomes), i.e., the X and Y chromosomes are called organic phenomenon characteristics or organic phenomenon traits. the first criteria for any of the traits to be organic

Humans are anatomically similar to and related to great apes, but they differ in having a more developed brain and, as a result, the ability to articulate speech and abstract reasoning. Furthermore, humans have a notable erectness of body carriage, which frees the hands for use as manipulative members. However, some of these characteristics are

Rh factor is found outside the red blood cells. It is also known as the Rhesus factor and is a type of protein. It is passed from one generation to another; it is genetically inherited from parents to the offspring. When a child does not inherit the protein from their parents, they become Rh-negative. Most

Rare diseases can be caused by genetic abnormalities. In the United States, less than 200,000 persons are affected by this group of illnesses. Experts estimate that there could be as many as 7,000 cases. The basic functional unit of heredity is the gene. Genes are made up of DNA, which contains the genetic information that

The movement of genetic material from one group to another is known as gene flow. Gene flow is mediated by reproduction and vertical gene transmission from parent to offspring and may occur between two populations of the same species.  Random changes in the number of gene variants in a population are referred to as genetic

A Punnett square is a graphical representation of the genotypes that an offspring could have as a result of a specific cross or breeding event. Creating a Punnett square necessitates knowledge about the parents’ genetic profile. In a tabular arrangement, the many conceivable combinations of their gametes are contained. As a result, each box represents

Lethal, often referred to as fatal genes or lethal alleles, are alleles that cause the death of the entity that possesses them. Essentially, lethal genes are lethal to organism that carries them, with fatal referring to death. It is usually the result of gene mutations that are necessary for growth and development. When researching the inheritance

Any gene that has an effect on the organism’s death at any stage of life. A gene that has a profoundly unfavourable effect on the phenotypic and causes the organism to exhibit numerous adverse features, which might eventually result in death. A deadly gene is one that results in an organism dying before reproduction is
