Honey bees (Apis sp.) often exhibit a state called haplodiploidy that really throws off the 1:2 or 1:2:1 ratio since it's only the female offspring that have the condition.
According to our lecture today, the highest ploidy number is 38. The caveat being that research is ongoing and that number will likely get larger.
Also there can exist more that one ploidy condition within the same plant if a mutation occurs on the apical meristem.
Fascinating stuff indeed. But I'm a plant geek working on my master's degree in Ecology.
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.
