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.
âConsidering the potential dangers outdoors, an indoor lifestyle is much safer for cats,â Brunt says. As evidence, indoor cats live longer than their outdoor counterparts. Cats who are kept indoors can reach the ripe old age of 17 or more years, whereas outdoor cats live an average of just two to five years. Another reason for indoor catsâ longevity is that itâs easier for their owners to identify health problems early, before they become life threatening.
