Describe the effect that sickle cell anemia has on the sedimentation rate (sample 3. why do you think that it has this effect?
Eva8 [605]
Sickle cell anemia is a genetic condition that distorts the shape of the hemoglobin. This reduces the capacity of the red blood cells to carry oxygen. Another effect is that the distorted red blood cells come together forming a heavy and compact collection of cells that can block the flow of blood. The sedimentation rate is increased by sickle cell anemia.

Use a Punnett square diagram to show why, for each pregnancy, the chances of giving birth to either a boy or a girl are 50-50. E
ikadub [295]

Answer:

Because the offspring of a male and female are always going to be xx, xx, xy, or xy.

Explanation:

Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.

So we can write the this out in a punnet square as(link down below).

After you see the visual, you will find that the genotypes are xx, xx, xy, xy.

As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.

So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.
