Sex-linked Inheritance

Sex-linked Inheritance

Sex makes no difference in Mendel’s crosses. But the Mendel’s laws are not applicable on those genes which are exclusively located either in X or Y chromosome. Sex-Linked Inheritance is the inheritance of a trait (phenotype) that is determined by … Read more

Characteristic of Genetic Code

Characteristic of Genetic Code

The genetic code is the set of rules by which a linear sequence of nucleotides specifies the linear sequence of a polypeptide. That is, they specify how the nucleotide sequence of an mRNA is translated into the amino acid sequence … Read more

Hardy-Weinberg Equilibrium

Hardy-Weinberg Equilibrium

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law explains that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. The law was proposed by a British mathematician Hardy … Read more

Prokaryotic and Eukaryotic Chromosomes

Prokaryotic and Eukaryotic Chromosomes

The genome of an organism encompasses all of the genes of that organism. Gene is a distinct sequence of nucleotides forming part of a chromosome, the order of which determines the order of monomers in a polypeptide or nucleic acid … Read more

Chromosome- Structure, Types and Functions

Chromosome- Structure, Types and Functions

In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes were first described by … Read more
