The same sacrifice of a one year old lamb and young pigeon or turtledove applied for whether the baby was male or female. I'm thinking right now that God atones for everyone's sins without gender discrimination. I'm just trying to take a little feminist's perspective because I thought it would be fun to approach it in that context. I personally believe it's wrong to have a chauvinistic attitude and believe women are just as important as men, too. I favor either side more in certain situations though, just like I'm sure others would as well.
In addition, I notice that this verse was now using a young pigeon or turtledove instead of the bull or ram that was used for a sin offering. This is really interesting in that I'm not sure right now, if these animals were used differently only under God's discretion. The beginning chapters mentioned the different types of animals that were used, as it was listed out, but whatever God says would pretty go, I suppose, even though I don't fully understand this yet.
