Scientists have found that when giant pandas mate with their preferred partners, they mate more often and have more babies, but if they choose to mate with their relatives, that would lead to less genetic diversity. In some species, such as the moose, during the rutting period males mate with a succession of females. The trouble is, many breeding programs around the world have found they have greater reproductive success when they allow animals to choose their mates, like giant pandas. Females are also known to have cubs with many different fathers. Its recommended to avoid mating siblings as it can lead to unwanted DNA defects. The scientific evidence either way is essentially nil, although some researchers believe a dog has to have been with his or her littermates for at least the first 16 weeks of life to be able to recognize them later on. If there are two defective genes between the siblings and they pair up, their offspring will be noticeably defective. 2. Great learning needs awesome research!

They are the most intelligent native nonhuman animals in North America, and many modern bear biologists accredit them with the equivalent IQ of the great apes, some even dare give them the equivalent intelligence of a 3-year-old human. This means that the intercourse causes the ovaries to release eggs. Brown bear siblings live together for several months before they also go their separate ways.
