Researchers selected candidate genes by identifying homozygous tracts shared by all three siblings. along with the parental phenotype, what does this suggest regarding the inheritance pattern of dyt2?
a. it is recessive because the father was neurologically normal and it is autosomal.
b. it is dominant because the mother was neurologically normal and it is autosomal.
c. it is recessive because the father was neurologically normal and it is x-linked.
d. it is dominant because the mother was neurologically normal and it is x-linked.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

the answer is a for sure mark brainliest i had got this right on usatestprep
