Straight wings are dominant over curved wings

Let Straight wings : H

curved wings : t

smooth eyes are dominant to sparkling eyes

let smooth eyes = H

spark ling eyes = t

tan body is dominant to ebony body color.

Again; Let tan body color be H

Let ebony color be t

If flies that are heterozygous for all three traits are crossed;

we have HtHtHt × HtHtHt

Then the selected trihybrid traits for the cross will be (HHH,HHt, HtH, Htt, tHH, tHt, ttH, ttt)

We will realize that from the punnet square in the diagram below, the proportion of the offspring would you expect to be heterozygous for all three traits (i.e HtHtHt) is asterisk in the punnet square and will be \frac{8}{64}

= \frac{1}{8}

This is called bursitis specifically olecranon bursitis. Olecranon bursa in the elbow is a thin fluid filled sac at the tip of the elbow. The bursa fills with fluid which can lead into inflammation on the surrounding area of the elbow resulting in pain and limitations of movement. Complications can happen if medical attention is not given. This includes bleeding, bruising, infectins, necrotizing fasciitis can also happen. Patient must undergo work up such as plain x rays, bone scintigraphy or if needed MRI/CT scan. Surgical interventions are usually needed because non surgical means are usually non effective. Long term monitoring is a must and patient must be advised on prevention practices.

This clearly tells that most of the carbon in earth is stored in soil and air. The movement of carbon within the biosphere makes up the carbon cycle.
