What did people think about traits before Mendel? Before Mendel, people believed that the traits of offspring were simply blends of their parents e.g tall + short parent = medium offspring What did Mendel discover about traits of pea plants? Tall pea plant + short pea plant = all tall offspring pea plants. From this he figured out each parent must have a unit passed directly to the offspring that determine height. We call those units genes.
The average domestic cat lifespan comes out to 15.1 years. Breed is certainly a factor. We could list out each breed, but then weâd be here forever. Our research suggests that mixed breed cats are, in general, hardier and live longer than purebred cats.
The reality is there are numerous factors that determine 'cat age' or the life span of a cat.

Naturally, there are exceptions to every rule and we have read about cats that have lived for over 30 years. Cat life span can be affected by any of the following: indoor cats vs the outdoor cats. cat nutrition.
