Chromosomal theory of inheritance, linkage, sex determination

Introduction Gene flow refers to the transfer of individual genetic material from one person to another. There are many types of events involved in this process, such as people moving to a new area or pollen being driven to a new location. It can lead to significant genetic variation if the versions of gene flow […]

Individuals within each species have their own collection of genes. A gene is a hereditary unit that allows future generations to inherit the characteristics of their parents. The nucleotide sequence in the DNA strands is bundled in chromosomes referred to as genes.  Genes determine the differences and similarities across various organisms. They are responsible for

Introduction Alleles are a type of gene that is responsible for changes in the phenotypic expression of a trait, such as brown vs green eyes. The term polymorphism refers to a gene that has at least two alleles. Multiple allele circumstances are defined as situations in which a gene can occur in three or more

Genetics is the study of heredity, which refers to the features we inherit from our parents and their parents and so on. Coded information found in every cell of the body controls these characteristics.DNA, genes, and chromosomes are the components of heredity. This page provides a basic understanding of genetics, including genes, DNA, and chromosomes

Pleiotropy is a phenomenon that takes place when a single gene affects many properties in living organisms A gene mutation can result in pleiotropy. Pleiotropy can be seen in the human genetic disorder Marfan syndrome, which affects the connective tissues. This illness commonly affects the eyes, heart, blood vessels, and bones. Pleiotropy is caused by a

The introduction and establishment of genes from one breeding population into another’s gene pool. The introduction of novel alleles via gene flow enhances population diversity and allows for new trait combinations. Gene flow occurs in humans mostly as a result of the voluntary or forced movement of human groups. In the case of migration, the

A mosquito belongs to the family Culicidae, about 3,500 species of familiar insects in the fly order, Diptera, are very much important in public health due to the bloodsucking habits of the females. Mosquitoes are commonly known to transmit serious diseases, like yellow fever, zika fever, malaria, filariasis, and dengue. Like all other true flies,

Gene and DNA are two terms that are typically used in the field of genetics to refer to genetic material. In general, a gene is a short segment of DNA, and DNA-deoxyribonucleic acid is a molecule that carries the genetic instructions or the hereditary materials, as defined by the International Code of Genetics and Genomics.

Introduction Gregor Johan Mendel is considered the father of genetics who first introduced both monohybrid and dihybrid cross. Mendel chose pea plants as their genes do not show the property of linkage. He formulated his two laws, the law of segregation and the law of independent assortment based on monohybrid cross and dihybrid cross respectively.

Introduction The molecular basis of inheritance is the examination of genes, hereditary and genetic versions. The molecular basis of inheritance is the reason why an offspring seems much like its maternal or paternal features. DNA, RNA, and genetic code are the essential elements of the molecular foundation of inheritance and are accountable to transmit genes
