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.
Ageing and your feline. Cats are living longer than ever. With improvements in nutrition and veterinary medicine including vaccines and therapeutic agents, cats are living to over 15 years of age and in some cases over 20 years of age. Life expectancy depends on many things, including one important factor - whether your cat is an indoor-only cat or an outdoor cat. Indoor cats generally live from 12-18 years of age. Many may live to be in their early 20s. The oldest reported cat lived to be an amazing 28 years old. Outdoor cats generally live shorter lives due to being more likely to be involved in traumas such as motor vehicle accidents or dog attacks.
