Answer AND Explanation:

Let H be for normal blood clotting gene.

               XH            Xh

XH         XHXH      XHXh

Y            XHY          XhY

The probability of the couple having a hemophilia sex-linked trait is 25% and 75% for normal children.

Some people seem more willing to openly display prejudice regarding sexual orientation than prejudice regarding race and gender.
STALIN [3.7K]

Answer:

Some people offer more prejudice on the sexual orientation because sexual orientation like gay marriages were not seen in the world before. Before the 21st century, the same- sex marriage was never seen or heard about. So, today people display more prejudice regarding this issue because sexual orientation began in the 21st century. Many people are of the view that this same sex marriage is not traditional and hence it is not right morally. While others believe that every person has the right of freedom and this is their civil right to do what they like.

The discrimination based on race and gender has been an issue from the start of human lives. Almost every country has a history which shows race and gender discrimination. Hence, though majority of the people today are against this but still is is not as a hot and new topic for prejudice as the topic of sexual orientation is.

In the currently accepted atomic model, an electron orbits the nucleus in a<br> clear, defined path.
Alex777 [14]

FALSE

In the currently accepted atomic model, an electron orbits around the nucleus is NOT in a clear, defined path.

Explanation:

According to modern atomic models, like the Bohr theory, it is difficult to know the exact location and path of an electron around the nucleus. This is partly because the mere act of observing the electrons changes its position. This is because the electrons have negligible mass and therefore ‘hitting’ them with any form of radiation for ‘illumination’ changes its position, behavior, and properties. In addition, the movement of electrons is very rapid such that by the time one observes the instantaneous location of an electron, if it was possible, it will have changed its position.

Therefore modern theories, such as VSPER, model atoms based on properties of where an electron will highly likely be found. This is how the shells and subshells of electrons (s, p, d, f) are modeled.
