<span>without myelination, information about limb movement moves slowly to the CNS and motor commands move slowly back to the muscles. by the time the motor command has reached the muscle, it may no longer be appropriate. as the neurons become myelinated, the speed of action potential increases which is why we observe improved balance, coordination, and movement.</span>

Answer: The man's genotype is WwLt while the woman's genotype is wwLt.
Explanation: From the information given above, W is the allele for wide jaw, w is the allele for narrow jaw, W is completely dominant to w, L is the allele for large teeth while t is the allele for small teeth.
The man has wide jaw but his mother has a narrow jaw, since narrow jaw is recessive the man must have inherited one recessive allele for narrow jaw from his mother who has two recessive alleles for narrow jaw. Therefore since the man has wide jaw, he must be heterozygous for wide jaw (having one dominant allele for wide jaw and one recessive allele for narrow jaw), his genotype for wide jaw is therefore Ww. The man is heterozygous for teeth size, this means that he has one dominant allele for large teeth and one recessive allele for small teeth. His genotype for teeth size is Lt. Therefore the man's genotype is WwLt.
The woman has a narrow jaw, this means that she has two recessive alleles for narrow jaw (ww) and she is heterozygous for large teeth size, this means that she has one dominant allele for large teeth and one recessive allele for small teeth (Lt). Therefore, the woman's genotype is wwLt.
Huntington's disease is a hereditary condition in which your brain's nerve cells gradually break down. It affects your physical movements, emotions, and cognitive abilities. There is no cure at the moment, although there are ways to cope with this disease as well as it's symptoms. Genetic testing can definitively diagnose this condition, it may also help you decide whether or not to have children. Some people don't want to risk their children having this defective gene. Symptoms that may occur as the disease progresses include, uncontrolled twitching, difficulty walking, trouble swallowing and speaking, confusion, memory loss, personality changes, speech changes and decline in cognitive abilities. Sorry about the long post! Hope this helps ya'!
