Explain Mendel\'s concept of heredity, by giving three points? |
| Answer» Our understanding of how inherited traits are passed between generations comes from principles first proposed by Gregor Mendel in 1866. Mendel worked on pea plants, but his principles apply to traits in plants and animals – they can explain how we inherit our eye colour, hair colour and even tongue-rolling ability.Inheritance in pea plantsMendel followed the inheritance of 7 traits in pea plants (Pisum sativum). He chose traits that had 2 forms:\tPea shape (round or wrinkled)\tPea colour (yellow or green)\tFlower colour (purple or white)\tFlower position (terminal or axial)\tPlant height (tall or short)\tPod shape (inflated or constricted)\tPod colour (yellow or green). | |
