Males. Female rats tend to be more active.
Male rats tend to get lazy as they mature.
Yes we have a male and when we got him the others were all female at the store and he was the calmest!
Female rats don't just turn into male rats. Sometimes a male rat's testes will be withheld in his body as a result of stress and he will appear to be female. Of course in such a situation, he is still male.
a male is stronger
male or female!!
It depends on how they were raised, but generally Female dogs are calmer. If you happen to get a Male dog its most likely people will tell you that if you get him "fixed" it will make him calmer. This is a myth.
i think so
male facks female..
There are various different experiements performed on rats, & they quite often vary between male & female results. Male rats are not a high choice for experiments, but should a test to be used for men need to be created, then male rats would be the test subjects, & vice versa for females/
10685 male rats and 9567 female rats.
A steer is more likely to be calmer, just like a castrated male dog is probably calmer than a unfixed female because they have less hormones in their body. they also have better tasting meat because of it
No, rats have intercourse to have babies, and there are both male and female rats.
