What is Heterosis? Heterosis, commonly known as hybrid vigor, refers to the phenomenon where the offspring of two genetically different parents exhibit greater vigor, growth, yield, or other desirable traits than either of the parent strains. This increased performance in hybrids is a key concept in plant breeding and agriculture. Here’s a closer look at … Read more

What is Dominance Hypotheses? The Dominance Hypothesis refers to a concept in plant breeding and genetics that deals with the expression of traits in offspring based on the dominance of alleles. It essentially posits that in a heterozygous state, one allele (the dominant allele) can mask the expression of another allele (the recessive allele). Here’s … Read more

What is Pureline Selection? Pureline selection is a plant breeding method used to develop new varieties from a single genotype or “pure line.” This approach is based on selecting and propagating individuals that consistently exhibit desirable traits, aiming to create a genetically uniform and stable line. Here’s how it typically works: Pureline selection is particularly … Read more

What is bulk Method? The bulk method is a plant breeding technique used to develop new varieties by selecting plants with desirable traits through repeated cycles of selection and propagation. Here’s a brief overview of how it works: The bulk method is often used in the early stages of breeding programs to quickly evaluate and … Read more

What is Backcross Method? The backcross method is a genetic technique used in plant breeding and animal genetics to transfer a specific trait from one organism to another while maintaining the genetic background of the recurrent parent. This method involves several key steps and objectives: Key Concepts of the Backcross Method Advantages of the Backcross … Read more

What is Gene? What is Allele? Differences Between Gene and Allele Understanding the concepts of genes and alleles is crucial in genetics. While both terms are fundamental to the study of heredity, they refer to different aspects of genetic information. Here, we explore the distinctions between genes and alleles, outlining their roles and characteristics in … Read more

What is Linkage? What is Crossing Over? Difference Between Linkage and Crossing Over Here is a detailed comparison of these two genetic phenomena: Aspect Linkage Crossing Over Definition Tendency of genes close on the same chromosome to be inherited together during meiosis. Exchange of genetic material between non-sister chromatids of homologous chromosomes. Relationship of Related … 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 Polyembryony? What is Apomixis? Characteristics of Apomixis Characteristics of Polyembryony Differences Between and Apomixis Characteristics of Apomixis vs. Polyembryony Category Apomixis Polyembryony Offspring The offspring are genetically identical to the parent plant. This is because the embryos are produced asexually from the parent’s cells. The offspring can either be genetically identical or genetically … Read more

The fact that they are both cells that are eukaryotic, meaning they have a real nucleus that is enclosed and separate from other organelles through a nuclear membrane is a key element which determines their ways of multiplication. They share the same reproduction process of meiosis and mitosis by using their DNA, which is stored in the cell’s nucleus.
