Mendel’s Laws of Segregation, Independent Assortment and Dominance

Mendel’s Laws of Segregation, Independent Assortment and Dominance

Mendel’s Laws of Segregation, Independent Assortment and Dominance This new theory of inheritance was first proposed in the early 1860s by an Austrian monk named Gregor Mendel depending on his experiments with pea plants at the University of Vienna. Heredity was Mendel’s belief, and each unit (or gene) in an individual’s genome acted independently of … Read more

Transcription Vs Translation: Definition, Differences, Examples, Diagram

Difference between Transcription and Translation

Transcription Definition (What is Transcription in Biology) Transcription is the process of transferring genetic information from a DNA strand to an RNA strand through a sequence of polymerization processes catalysed by DNA-dependent RNA polymerases. The information is passed on from one structure to another in the first phase of gene expression. RNA molecules are begun, … Read more

Monohybrid Cross: Definition, Steps, Diagram, Examples

Monohybrid Cross: Definition, Steps, Diagram, Examples

Monohybrid Cross Definition A monohybrid cross is a genetic cross between two individuals who have homozygous genotypes for a single feature or trait, with the phenotype often being the polar opposite. Monohybrid crossings are commonly used to ascertain the genotypes of homozygous individuals’ progeny. The hybrid resulting from this cross aids in the determination of … Read more

Homozygous Vs Heterozygous: Definition, Differences, Examples

Homozygous Vs Heterozygous: Definition, Differences, Examples

Homozygous Definition Homozygous is a genetic situation in which a person inherits the same alleles from both parents for a gene. Both alleles are dominant or recessive in homozygous chromosomes. Two capital letters (XX) denote the dominant trait, while two lowercase letters denote the recessive trait (xx). Homozygous-dominant chromosomes have two copies of the dominant … Read more

Phenotype Vs Genotype: Definition, Differences, Examples

Phenotype Vs Genotype: Definition, Differences, Examples

Phenotype Definition  In genetics, phenotype refers to all observable features in organisms that are the outcome of the genotype’s interaction with the environment. Phenotype is derived from the Greek word pheno, which meaning “observation.” Phenotypes are used to describe observable features in animals such as height and colour. A phenotype describes an organism’s morphology, physical … Read more
