About 70% of Americans perceive a bitter taste from the chemical phenylthiocarbamide (PTC). The ability to taste this chemical r

esults from a dominantallele (T) and not being able to taste PTC is the result of having two recessive alleles (t). Albinism is also a single locus trait with normal pigment being dominant(A) and the lack of pigment being recessive (a). A normally pigmented woman who cannot taste PTC has a father who is an albino taster. She marries a homozygous, normally pigmented man who is a taster but who has a mother that does not taste PTC. What are the genotypes of the possible children (choose all that apply)

The genotype for the possible children is 'AATt, AAtt, Aatt, AaTt'.  Woman has normal pigment which means she must have at-least one' 'A. her father is albino and albino allele is recessive , so his genotype is 'aa'. Then 'Aa' genotype is present in skin.

Woman cannot taste PTC because the ability ti taste PTC is dominant .So 'tt' genotype is present for tasting trait. Putting both the trait the woman's genotype is 'Aatt'.

(PTC) Phenylthiocarbamide tasting is  a trait governed by pair of alleles ,  'T' is for tasting dominant and recessive 't' is for non- tasting.The genotype of parents perform a punnett square to determine the F1 offspring. And the genotype of possible children can be determine.

The muscle action can be determined by:

* Prime Movers and antagonist: Prime movers are also called the agonist, it is the muscle that provides the force that drives the action. Regarding to the antagonist muscle, it is the opposite to a prime mover as it provides resistance or reverse in a given movement. They are paired up on opposite sides of a joint.

* Synergists: There are one (or more) synergists involved in an action, the are muscles that help the prime mover when it is playing its role.

* Stabilizers: Their fuction is to keep bones immobile when it is needed. For example, the muscle of your back, they are stabilizers when the keep your posture sturdy.
