:the numbers refer to how many of each sex a person has... 1.0 would be 1 male, 0.1 would be 1 female. 1.4 would be one male and 4 females. Sometimes there is a third number, like 0.0.1, which refers to how many of unknown gender. So 1.3.2 would be one male, 3 females, and 2 unknown.
:'Het' is short for heterozygous, which means that the animal carries one copy of a recessive gene, and appears normal. When a anery is bred to a het anery, half of the offspring would be anery, and half would be het anery.
