生物的性状是由基因控制的,基因的位置不同,其所控制的性状的遗传特点也不同,有些性状遗传方式之间表现出很大的相似性。下面结合几道例题谈一下不同遗传方式的区分方法。一、细胞质遗传与种皮、果皮的遗传种皮、果皮分别是由母本的珠被和子房壁发育形成的,因此种皮、果皮的基因型和性状均与母本相同,因种皮、果皮为母本一部
Biological traits are controlled by genes. Genes are located at different positions, and the genetic traits controlled by them are also different. Some traits of genetics show great similarities. The following combination of several examples talk about the method of differentiation of different genetic methods. First, the cytoplasm of the genetic and seed coat, peel genetic seed coat, peel were from the mother of the beads and ovary wall development formation, so the seed coat, peel genotype and trait are the same as the female parent, due to the seed coat, Peel as a female parent
