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.
Indoor Cats. Indoor cats can live a long life, provided they're well taken care of and they're in good health. On average, indoor cats live 12 to 15 years. A cat may reach the age of 21, if he doesnât have any medical conditions and has a proper diet.
I've asked many people the same thing and have had many cats of my own. Cats can live a long time but it can also depend on the breed. The longest a cat can live is about 18-20 years. Source(s): My vet, cats101, cats encyclopedia book.
