None of those mice seem to have seminal plugs either so it looks like they have not seena male or you would think atleast one would be pregnant.
how did i get caught up in a decussion on mice balls, really got to re think my sunday evenings on this site.
only girls have nipples thats a dead give away
They all have vaginal openings......
Can you see nipples on all of them?
not true... in the same way i have nipples... so do males in almost all mammal species.... the female nipples in mice however do develope earlier and are more prominant....
2,5 and 6 look male but it's hard to tell cause their tails are up over their heads. sit them on your hand and relax their tail. if you see two huge jajoombas then it's a boy. they are not hard to sex
What Nagini said is correct although she should have been more specific, only females have visible nipples, males do have them, but they are barely visible
i dont wanna go on a rank here.... but i have had several males that have had clearly visible nipples.. and another of my family members that also breeds mice has mis-sexed many mice by thinking "only girls hav nipples u can see"
Fair enough, I always thought it was pretty reliable from sexing hundreds this way
maybe its just the strain/strains you've work with... but i can assure u its not a 100% accurate way to sex mice.. like has been suggested...
should i take 3 back to the pet shop and get a different 3 males? And should i check b4 i get them?
