Answer:
1/6
Explanation:
Assuming the disorder is not sex linked, Charles is a carrier so he will be Ff.
His wife Elaine can be a carrier or not because her parents must have been both Ff
Possible F1 generation for her was FF, Ff, Ff and ff. She does not have the disease.
Therefore the total chance of her having FF was 1/3 whereas Ff will be 2/3
Probability of the kid having the disease will be calculated by;
(2/3×1/4) +(1/3×0)= 1/6
Answer:
The genotypes of the two parents: normal head shape (HH) and Bart head shape (hh)
The genotypes in the F1 generation= Hh
The phenotypes present in the F1 generation= All normal head shape
Explanation:
Let's assume that the allele "H" is responsible for the normal head shape while the allele "h" gives Bart head shape. According to the given information, both the parents are homozygous. The genotype of the parent with normal head shape would be "HH" while that of the one with Bart head shape would be "hh". Since the normal head shape is dominant, all the F1 hybrid progeny would exhibit "normal head shape".
Answer:
Option (A).
Explanation:
Muscle contraction may be defined as the physiological process of the activation of tension generating sites that occur within the muscle fibers. Actin, myosin, troponin and other proteins are important for muscle contraction.
The calcium ion is important for the muscle contraction. The binding of calcium with troponin causes the movement of tropomyosin out of the grooves between the actin molecules during muscle contraction.
Thus, the correct answer is option (A).
