Thekey differencebetween blending and particulate inheritance is thatin blending inheritance, offspring is a blend of both parents, while in particulate inheritance, offspring is a combination of both parents.
Genes are the basic units of inheritance. Offspring receives genes or substances of inheritance from their parents (mother and father). Blending inheritance and particulate inheritance are two theories in biology which explain the inheritance oftraitsto offspring. According to blending inheritance theory, offspring receives an intermediate or average phenotype of the parent phenotypes. According to particulate inheritance, offspring receives one gene from mother, and one gene from father and they are expressed independently without blending. Blending inheritance was dismissed by the theory of particulate inheritance.

什么是混合继承?
融合遗产是一种早期理论,称后代从父母那里融合了遗传物质。因此,后代显示了父母之间的中间特征。换句话说,混合理论说,两个父母与父母之间的特征产生了后代。因此,后代只是父母的两个不同特征之间的平均值。作为解释这一理论的一个例子,我们可以考虑产生白花和红色花朵的两个品种的交叉。如果该十字架产生粉红色后代,则显示出融合的继承。
However, this theory is now an obsolete theory – it is no longer accepted. Moreover,natural selectionis not possible if the inheritance takes place according to the blending inheritance.
What is Particulate Inheritance?
颗粒遗传是Gregor Mendel解释的理论。它指出,离散的颗粒或基因从父母传递到后代。来自父亲和母亲的基因在后代独立表达而无需合并或混合。此外,基因一代传播。
Recessivegenes may not be expressed due to the dominant gene, but they remain and keep their ability to be expressed in a later generation when they are in a homozygous state. Mendel proposed this theory by carrying out experiments on pea plants. He also explained thatgenetic variationcan be inherited and maintained over time.
What are the Similarities Between Blending and Particulate Inheritance?
- Blending inheritance and particulate inheritance are two theories postulated to explain the inheritance of genetic materials from parents to offspring.
What is the Difference Between Blending and Particulate Inheritance?
Blending inheritance states that an offspring is a blend of parent’s values of that characteristic. In contrast, particulate inheritance states an offspring receives discrete units or genes from its parents without blending. Therefore, offspring is a combination of both parents. So, this is the key difference between blending and particulate inheritance. Blending inheritance was postulated in Darwin’s time while particulate inheritance was explained by Gregor Mendel.
Moreover, blending inheritance is an obsolete theory, while particulate inheritance is an accepted theory.

概括– Blending vs Particulate Inheritance
融合遗产指出,后代始终是父母特征的中间融合。相反,颗粒物的继承指出,后代从父母那里接收离散单位。混合遗传理论不再是公认的理论,而颗粒遗传是生物学中公认的理论。遗传变异是根据颗粒遗传遗传和维持的,而根据混合遗传,遗传变异是不可能的。因此,这是混合和颗粒遗传之间差异的摘要。
