Following statements are regarding to Shivering, which is the most potent mechanism for increasing heat production in the body. 

A. Cold environmental temperatures activate centers in the posterior hypothalamus during shivering, which then activate the α and γ motoneurons innervating skeletal muscle. 

B. Shivering involves skeletal muscle contracts rhythmically, generating heat and raising body temperature.

C. Shivering involves stimulation of Na+-K+ ATPase and raising body temperature.

D. Shivering involves stimulation of β receptors in brown fat, which increases metabolic rate and heat production.

A certain kind of snail can have a right-handed direction of shell coiling (D) or left handed coiling (d). If direction of coiling is due to a protein deposited by the mother in the egg cytoplasm, then a Dd egg-producing snail and a dd sperm-producing snail will have offspring of which genotype(s) and phenotype(s)?
