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.
Veterinary medicine has made some great advances in recent years, and this is one of the reasons the average age of domestic cats is increasing. A well cared for cat that is kept indoors and is fed a good nutritional diet, would be expected to live for about 15 years. Some cats do live to 20 plus years and there are records of a few cats reaching over 30 years. These sort of ages for a cat are very much the exception however. The genetic make up of a cat can be a factor in determining its life span, some breeds of cat appear to be more resilient than others.
