Principles Of Inheritance

Principles of inheritance Inheritance is defined as the process in which genetic material is passed from parents to offspring. We have diploid chromosomes (23 sets of chromosomes), but gametes ( also known as egg and sperm) have one set of chromosomes, thus called as haploid. We contain one copy of genetic material (chromosomes) from each […]

Gene Flow

Gene flow is transfer of genes from one population to another. Factors affecting gene flow: 1. Mobility: gene flow is lower in species having low mobility or dispersal. 2. Distance: When there is long distances between populations then it results in low gene flow. 3. Population size: Small population size results in low gene flow. […]

Lipid Bilayer

Lipids in cells have three main functions: energy storage, signal transduction and forming the matrix of biological membranes. Lipid membrane have asymmetric distribution of lipids between two leaflets. Cell membrane composed of polar lipids that self assemble to form bilayer. Thus, cell membrane forms asymmetric structure which means two sides of membrane are functionally and […]
