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.
Typical Indoor Cat Lifespan. If a cat resides indoors exclusively, the typical lifespan ranges somewhere between 13 and 17 years, according to the ASPCA. However, it isn't uncommon for indoor cats to live to at least 20. The lifespan always depends on the individual cat. Some cats pass away well before 13, while others live long past 17. A lot of factors go into how long a cat will live.
