What is the expected phenotypic ratio for feather colour if two chickens with blue feathers are crossed
ss7ja [257]

Answer:

The correct answer is - 1:2:1 for black : blue : white chicken.

Explanation:

We know that color of the feather is a trait of the chicken that shows the codominance type of inheritance pattern where both forms of the trait are dominant and make a mix of the forms. In this case, blue is heterozygous BW and black BB and white is WW, then crossed between BW with BW

gametes: B, W and B, W

Punnett

           B       W

B        BB      BW

W        BW     WW

thus, the phenotypic ration is - 1 black : 2 blue : 1 white

In arteriosclerosis, overproduction of abnormal collagen and decreased quantities of elastin lead to what?
Tcecarenko [31]

In arteriosclerosis, overproduction of abnormal collagen and decreased quantities of elastin lead to Decreased coronary artery perfusion.

Arteriosclerosis is a condition in which the arteries, which transport oxygen and nutrients from the heart to the rest of the body, thicken and stiffen, often limiting blood flow to the organs and tissues. Flexible and elastic arteries indicate good health. However, the artery walls can stiffen over time, a phenomenon known as arterial hardening.

The accumulation of lipids, cholesterol, and other chemicals in and on the artery walls is known as atherosclerosis. The accumulation is known as plaque. Atherosclerosis can constrict the arteries and obstruct blood flow. The plaque may rupture and cause a blood clot.

Symptoms of arteriosclerosis:

  • chest pressure or discomfort (angina)
  • sudden numbness or weakness in the arms or legs.
  • speech slurs or speaking difficulties.
  • vision briefly lost in one eye.
  • weakened facial muscles
  • ache while walking.
  • elevated blood pressure
  • renal failure
