Multiple Choice

In the context of Mendel's experiments and laws, why might the term 'successful mistakes' be used to describe certain chromosomal events?

Because some chromosomal mutations can lead to beneficial traits that are favored by natural selection.

Because Mendel intentionally introduced errors to observe their effects.

Because chromosomes never undergo any changes during inheritance.

Because all chromosomal mistakes always result in nonviable offspring.

Verified step by step guidance

Understand the context of Mendel's experiments, which focused on inheritance patterns and how traits are passed from parents to offspring.

Recognize that the term 'successful mistakes' refers to chromosomal mutations or changes that occur during cell division or reproduction, which are essentially errors in the genetic material.

Recall that not all chromosomal mutations are harmful; some can produce new traits that may provide an advantage to the organism in its environment.

Connect this idea to natural selection, where beneficial mutations increase an organism's chances of survival and reproduction, thus becoming more common in the population over time.

Conclude that 'successful mistakes' describes chromosomal mutations that, despite being errors, result in beneficial traits favored by natural selection, explaining why this term is used in genetics.
