The muscle that inserts on the acromion and scapular spine is the Trapezius.
The trapezius muscle inserts into the scapular spine acromion and posterior superior lateral clavicle. Contraction of its various parts thus allows the scapula to be lifted, suspended, stabilized, and rotated. inserted. The deltoid muscle inserts into the acromion process, the main muscle that raises and extends the arm.
In humans, the acromion process can be flat curved hooked, or convex depending on the shape. The intrinsic muscles of the scapula include the rotator cuff teres major subscapularis teres minor and infraspinatus. These muscles attach to the surface of the scapula and assist in the abduction and external and internal rotation of the glenohumeral joint.

Albinism is a recessive trait. A man and woman who both have normal pigmentation have one child out of three who has albinism (without melanin pigmentation). The genotypes of this child's parents: (C) Both parents must be heterozygous.
Albinism is an autosomal and not a sex-linked recessive trait.
Only homozygous recessive (aa) offspring will be albino, both homozygous dominant (AA) and heterozygous dominant (Aa) offspring will possess the normal phenotype.
Since it is given that both the father and the mother have normal pigmentation, thus they must both have the genotype Aa.
From the Punnett square it can be observed that a cross between the parents would result in the creation of three offspring with the normal genotype (one with AA and two with Aa) and one offspring with the genotype aa (albino).
