Document Summary
Blending theory of inheritance: theory suggesting that hereditary traits blend evenly in offspring through mixing of the blood of the two parents. Mendel established that characters are passed to offspring as genes. Saw that many traits appear unchanged, and can disappear so that they don"t blend evenly. Mendel didn"t know but the inheritance parents were because o the segregation of chromosomes , where the genes are located in meosis. Prevented self fertilization and made sure that pollen to fertilize flowers came from a different plant - technique called cross-pollination. Cross fertilized plants make seeds that can be smooth/wrinkled or can grow into plants and be a certain flower colour. One gene from each parent- they can be same/different. Different alleles- one is dominant over the other, dominant is which explains appereance. 4) the adult plants carry a pair of factors that govern the inheritance of each character.
