Mendel’s experiments, which observed the independent segregation and assortment of traits, align with this mechanism of inheritance. The presence of two copies of each chromosome in germ cells, with one from each parent, allows for the inheritance of traits independently and explains the patterns observed in Mendel’s experiments. Additionally, this mechanism is not limited to sexually reproducing organisms; asexually reproducing organisms also follow similar rules of inheritance.
Why does the described mechanism of inheritance, involving chromosomes from both parents, explain the results of Mendel’s experiments?

The described mechanism of inheritance involving chromosomes from both parents aligns with Mendel’s experiments because it corresponds to the principles of segregation and independent assortment. Mendel’s laws propose that each organism inherits one set of chromosomes from each parent during sexual reproduction. This process ensures the transmission of genetic information in a predictable manner, leading to the observed ratios of traits in offspring. The combination of chromosomes from both parents during fertilization contributes to genetic diversity, and the independent assortment of genes on different chromosomes explains the inheritance patterns Mendel observed, providing a foundation for understanding the heredity of traits in organisms.
