Gregor Mendel’s hybridisation experiment was conducted to study the inheritance of traits in pea plants. Mendel initially acquired true-breeding varieties of pea plants, meaning that they passed on their traits to each generation when crossed. He crossed plants that had different traits to see how the traits were passed on to the next generation. Mendel …

1. Heredity is determined by the transmission of discrete, indivisible units or factors from one generation to the next. 2. Different traits are inherited independently of one another. 3. There are two factors (or alleles) for each trait, one from each parent. 4. The dominant factor will always mask the presence of the recessive factor. …

Mendel’s first generation (or “P” generation) of his experiment involved crossing purebred plants with different traits, such as tall and dwarf. The resulting offspring (or “F1” generation) were all tall and had a dominant trait. In the second generation (or “F2” generation), the offspring of the F1 generation were crossed with one another. This resulted …

The first generation of plants that are self-pollinated will be genetically identical to the parent plant. This means that all of the offspring will be exact copies of the parent plant and will have the same genetic makeup. Self-pollination is the process of a plant transferring its own pollen to itself, without the help of …

Dominant Traits: Dominant traits are traits or characteristics that are genetically passed down from parent to offspring. They are more likely to be expressed in the offspring than recessive traits. Examples of dominant traits include curly hair, having dimples, cleft chin, widow’s peak, and freckles. Hidden Traits: Hidden traits are traits that are not immediately …

Gregor Mendel was a scientist who conducted experiments with plants in the 19th century. He is best known for his experiments with pea plants, which demonstrated the laws of inheritance. In his experiments, Mendel grew and cross-bred different varieties of pea plants to study the patterns of inheritance. He observed the outcomes of each cross …

The emergence of genetics as a field of scientific inquiry began in the mid-19th century when Gregor Mendel, a monk in what is now the Czech Republic, used experiments with pea plants to identify the principles of heredity. Mendel’s work was largely ignored until 1900 when Hugo de Vries and Carl Correns independently rediscovered his …

Genetics is the study of the transmission of traits from one generation to the next. It involves the study of genes and their effects on the phenotype of an organism. Genetics also includes the study of how different genes interact with each other and the environment to affect an organism’s development and behaviour. genitics, jenitics

Plants have several defence mechanisms that help them fight off germs. These include physical barriers, such as a waxy cuticle on the leaves that can keep out microbial invaders, as well as chemical defences, such as the production of antimicrobial compounds. Plants also have the ability to recognize and respond to the presence of specific …

Blood grouping is the process of determining an individual’s blood type. It is based on the presence or absence of certain antigens (substances that can stimulate an immune response) on the surface of red blood cells. The most common system of blood typing is the ABO system, which is based on the presence or absence …
