The patter of inheritance would support the hypothesis that the trait being studied is a recessive sex- linked trait found on the X chromosome "The trait is mostly expressed in males who have a maternal grandfather with the trait."
Explanation:
A pedigree chart is a illustration that displays the existence and arrival of phenotypes of a specific genetic factor or organism and its families from one group to the next, most usually individuals, show dogs, and race horses. A pedigree chart displays a family tree, and shows the members of the family who are affected by a genetic trait. This chart shows four generations of a family with four individuals who are affected by a form of colorblindness. Circles represent females and squares represent males.
Under a microscope, gram-positive bacteria (when dyed with the gram stain) appear in purple-colored structures due to the peptidoglycan cell wall.
<h3>What are gram-positive bacteria?</h3>
Gram-positive bacteria are microorganisms (bacteria) that may be colored with crystal violet stain due to the presence of a peptidoglycan-based cell wall.
In conclusion, under a microscope, gram-positive bacteria (when dyed with the gram stain) appear purple-colored structures due to the peptidoglycan cell wall.

<span>c. numbers of neutrons.</span><span>
Isotopes are atoms of the same element with the same number of protons and same number of electrons but with <span>different number of neutrons. They differ in the number of neutrons that is why they also differ in mass numbers. Since they have the same number of protons, they have the same atomic number.
For instance, when the nucleus of the isotope with a 68.926 amu, there are 30 protons and 39 neutrons in the nucleus. The best example for this is Zn (zinc-69 isotope) and Ga (gallium-69 isotope) which has 68.926 amu and 68.925 amu respectively. </span></span>
