F1 generation:
genotype = BW
Phenotype = Erminette offsprings
F2 generation:
genotype = BB (1): BW(2): WW(1)
Phenotype = 1 Black, 2 Erminette, 1White
Explanation:
This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).
According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)
Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:
Genotypic ratio = BB (1): BW(2): WW(1)
Phenotypic ratio = 1 Black, 2 Erminette, 1White
Answer:
The answer is Carotid Murmur.
Explanation:
The carotid murmur is the presence of an abnormal noise that is heard with the stethoscope placed on the lateral wall of the patient's neck, almost always due to a stenosis of the carotid artery; that is to say, there is a narrowing in the lumen of the vessel, decreasing the amount of blood that goes to the face, head and brain. This narrowness of the vessel is presented by the accumulation of plaques within the arteries (arteriosclerosis).
