So i have a german shepherd. when i try to walk him he jumps and bites me. not playful little nips either, like jaw clamping down on my arms hard. he hasn't ever broken skin but i'm covered in bruises. it's hard to get him to stop since he's jumping while doing it. i'll step on the leash to prevent him from jumping, but then he turns to biting my legs. what should i do to prevent him from biting and jumping in the first place?

Polydactyly is expressed when an individual has extra fingers and/or toes. assume that a man with six fingers on each hand and six toes on each foot marries a woman with a normal number of digits. having extra digits is caused by a dominant allele. the couple has a son with normal hands and feet, but the couple's second child has extra digits. what is the probability that their next child will have polydactyly? polydactyly is expressed when an individual has extra fingers and/or toes. assume that a man with six fingers on each hand and six toes on each foot marries a woman with a normal number of digits. having extra digits is caused by a dominant allele. the couple has a son with normal hands and feet, but the couple's second child has extra digits. what is the probability that their next child will have polydactyly? 1/8 1/32 3/4 7/16 1/2
