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.
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.
