What is Multiple Alleles? Definition of Multiple Alleles Multiple alleles are different forms of the same gene that exist at a specific locus on homologous chromosomes, resulting in more than two possible variations of that gene within a population. While an individual organism can have only two alleles for a gene, multiple alleles contribute to … Read more

What is Incomplete Dominance? Definition of Incomplete Dominance Incomplete dominance is a genetic scenario where the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes, with neither allele being fully dominant or recessive. Concept of Dominance In genetics, the concept of dominance revolves around the relationship between alleles of a single gene. To … Read more

Incomplete dominance is one of the mechanisms for dominance among heterozygotes in which the dominant allele does not fully overpower the phenotypic expressions of the recessive one, and there is an intermediate phenotype within the heterozygote.

What is Codominance? Definition of Codominance Codominance is a genetic scenario where two different alleles at a locus are both fully expressed in a heterozygote, resulting in a phenotype that displays traits of both alleles simultaneously. What are the Symbolism for codominant alleles? Examples of Codominance Codominance in Animals Codominance in Humans Codominance in Plants … Read more

What is Mendel’s Law of Segregation? Mendel’s Law of Segregation Definition Mendel’s Law of Segregation states that alleles for a trait separate during gamete formation, ensuring each gamete carries only one allele, randomly inherited from the parent. What is segregation? Principle of Segregation and its Importance Characteristics of Mendel’s Law of Segregation Examples of Mendel’s … Read more

What is Mendel’s Law of Independent Assortment? Definition of Mendel’s Law of Independent Assortment Mendel’s Law of Independent Assortment states that genes for different traits are distributed to gametes independently of one another, meaning the inheritance of one trait does not affect the inheritance of another. Characteristics of Mendel’s Law of Independent Assortment Examples of … Read more

What is Mendel’s Law of Dominance? Mendel’s Law of Dominance is one of the foundational principles of genetics, formulated by Gregor Mendel through his experiments with pea plants. It asserts that when two homozygous organisms, each possessing contrasting traits for a specific character, are crossed, only one of the traits will appear in the first … Read more

What is Mendelian Inheritance/Mendel’s Laws of Inheritance? Genetics Terminology of Mendelian inheritance These terms clarify how genes operate, how traits are inherited, and the relationship between genetic information and observable characteristics. Download the Cheat sheet pdf Mendel’s Experiment Gregor Mendel’s experiments between 1856 and 1863 laid the foundation for our understanding of genetic inheritance. Using … Read more

What are Prions? Definition of Prion A prion is an infectious, misfolded protein that causes neurodegenerative diseases by inducing abnormal folding of normal cellular proteins, leading to the accumulation of these misfolded proteins in the brain. Unlike other infectious agents, prions lack nucleic acids and propagate their abnormal structure through direct protein-protein interactions. Characteristics of … Read more

Animal cell are considered to be the fundamental living species belonging to the kingdom Animalia. They are eukaryotic cells which means they possess an actual nucleus as well as organelles, which are special structures which perform various functions. Animal cells don’t have specific organelles for plants, such as cell walls that support the plant cell or the chloroplasts, an organelle that is responsible for photosynthesis.
