The answer <span>is AB and aB
<span>A man is heterozygous for sickle cell anemia: Aa
</span></span>A man is <span>homozygous dominant for familial hypercholesterolemia: BB
So, his genotype is AaBB. He will give only one allele of two for each gene.
He can have 2 different combinations in sperm cells:
- AB
- aB</span>
A pedigree shows the genotypes of the family members
in autosomal recessive disorders, the diseased genes are inherited from the parents. For the person to get the disease both diseased genes should be there in the genotype as its a recessive disorder.
the dominant gene - H
recessive gene - h
for a person to get a disease, genotype should be hh, as its autosomal recessive. If the person is normal he/ she could have the genotype HH or could be Hh and thats called a carrier.
the offspring will receive one gene from the mother and one from the father
Answer:
It saves time
Explanation:
You don't have to draw unnecessary details for complex structures
I think the correct answer is ions.
An action potential occurs when a neuron sends information down an axon, away from the cell body. A neuron that emits an action potential, or nerve impulse is said to fire. These action potentials are generated by special types of voltage hated ion channels that are embedded in the plasma membrane of the cell.
