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.
Best Answer: Hi there...provided the cat sees a veterinarian for regular check ups, is spayed/neutered and is a healthy weight the average lifespan is between15-18 years. Some cats can live beyond 20 years: http://www.healthycatanddog.com/.
