Gregor Mendel's research on inheritance and genetic traits provided a mechanism for the variation observed by Charles Darwin in his theory of evolution. By demonstrating how traits are passed down from generation to generation through discrete units (genes), Mendel's work supported the idea of natural selection driving evolution by acting on heritable characteristics. This helped to reinforce Darwin's theory of evolution by natural selection.

In mendels experiment a trait that always disappeared in the f1 generation but reappeared in the f2 generation was called the?

recessive trait


What can be known about Mendels five-part hypothesis?

Mendel's five-part hypothesis, known as Mendel's laws of inheritance, includes the principles of segregation, independent assortment, dominance, recessiveness, and the law of uniformity. These laws explain how traits are passed on from parents to offspring, and laid the foundation for the study of genetics. Mendel's research with pea plants in the 19th century provided key insights into heredity and the transmission of genetic traits.


Is it true that Mendels principles apply not to just to pea plants but to other organism as well?

Yes, Mendel's principles of inheritance, such as the law of segregation and the law of independent assortment, apply to many other organisms beyond pea plants. These principles have been found to hold true in various animals, plants, and even humans, demonstrating their widespread relevance in genetics.


What happened in mendels experiments when a pea received two different alleles for the same trait?

Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.


Was Darwin influenced by Mendels ideas about genetics?

No, Darwin knew nothing about Mendel's ideas and work. His, Darwin's, heritability concept was absolutely wrong. There is a legend that Darwin had a copy of Mendel's work in his desk but could not read German. The veracity of this story is often challenged.
