Which of the following best describes the inheritance of a sex-linked trait? *

a recessive allele carried by females that affects only males
a dominant allele carried by females that affects only males
an allele carried on the Y chromosome that can affect both males or females
an allele carried on an X chromosome that can affect males or females

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
