Someone PLEASE help me understand this biology question!!!!!!!!

Yep, females are diploid, and males result from parthenogenic haploid eggs that begin development. If we were studying traits inherited by honey bees in a monohybrid F1 X F1 cross, the numbers in the ratio would add to 3 instead of 4.

Ah, I <3 bee genetics. The females in the hive are 75% related to each other, since the queen is the only one to breed with the drones, rather then the 50% if all females were able to breed. Bees are incredibly interesting in all aspects of their lives.

Not to keep this thread overlong but....

Yesterday I attended a seminar on Unisexual salamanders. The discussion path led to polyploidy in vetebrates and successive generations. Genome research has discovered diploid ancestors and current animals that are diploids (expected), triploid, tetraploid and pentaploid as well. Seems that they can add a genome at times and suffer no loss of fitness. It has something to do with cell division not using the meiosis phase during reproduction.

The lecture was 40+ years of research condensed into an hour-long presentation. But it was interesting as heck. The photos of chromosome stains were pretty amazing.
