Lower plants, microbes and animals reproduce by different methods (fragmentation, gemma, binary fission, budding, regeneration). Organisms reproduce through asexual and sexual methods. Asexual methods in angiosperms occur through natural or artificial methods.  The natural methods take place through vegetative propagules or diaspores. Artificial method of reproduction involves cutting, layering and grafting. Micropropagation is a modern method used to raise new plants.

External fertilization occurs in lower plants like algae but in higher plants internal fertilization takes place. A flower i...

Class 12 - Bio-Botany - Key points 2. Classical Genetics / பாரம்பரிய மரபியல்

Test cross: To determine the gametes of a plant that has the genotype AaBb it should be crossed with a plant that has the genotype aabb. Gametes calculation: A plant that has the genotype AABbCC produces two types of gametes. Polygenic inheritance: This is when multiple genes control a trait, an example being skin color in humans. Dihybrid cross phenotypes: When you cross RRYY with rryy you get seeds with yellow cotyledons and other combinations in the F2 generation. Test cross definition: This is when the F1 hybrid is crossed with a recessive genotype. Test cross ratio: When a heterozygous yellow seed plant is crossed with a seeded plant the F1 generation has a 50:50 ratio. Link...
