The representation of the genotypes is as follows:
Homozygous dominant for curly hair (James): CC
Heterozygous dominant for curly hair (wife): Cc
The curly or straight hairs are the phenotypes and CC or Cc is the genotype of parental alleles.
When the first child is born which means the F1 generation, the type of hair the child will have can be predicted by punnet squares.
The Punnet squares have been shown in the image.
From the above punnet squares, two out of four probable phenotype or genotype of curly hair is 2/4 = 1/2 or 50%, have CC as their genotype and are homozygous dominant for curly hairs.
Prokaryotic chromosomes are found in the nucleoid of prokaryotic cells, and they are circular in shape
Which form of natural selection on polygenic traits results in the creation of two distinct phenotypes? The answer is, <u><em>B. Disruptive selection</em></u>
Answer:
A. Renin levels increase with poor kidney perfusion
D. Nephrotoxic drugs are a cause of intrarenal failure.
Explanation:
Renin is produced in the kidney for angiotensin aldosterone hormonal system and it is helpful in maintaining the blood pressure and other metabolic activities. However when the renin level is high then it means the kidney has a perfusion issue .
Nephrons are kidney cells. When a drug which is toxic to them gets into the body system then it affects the kidney and may cause kidney failure.
