1. There will be a 50% chance the child will have a (bb/ blue eyes) homozygous recessive phenotype. There is a 50/50 chance the recessive allele (b) will be given by either the mother or father.
2. If the child has blue eyes (bb) it is a homozygous recessive phenotype. Blue eyes can never be hetrozygous becuase in this scenario the heterozygous phenotype gives the child brown eyes.
The correct answer is that "t<span>roponin holds the tropomyosin in place on the actin".
In excitation-contraction coupling, tropomyosin prevents the interaction between actin and myosin in resting muscles. In the event of excitation, there is release of calcium from the sarcoplasmic reticulum wherein the troponin will bind this calcium and will release tropomyosin and expose myosin enabling it to attach to actin and therefore facilitating muscle contraction.</span>
