When I mated two curly-furred beasties, I was struck by the ratio of progeny. Roughly half (99) had curly fur, roughly one quart
Ostrovityanka [42]

Answer:

Both are Homozygous

Explanation:

A Husband and Wife with curly haired husband(CC) and straight haired wife have all their children curly haired because the gene for curly hair is dominant than straight hair. So, in the progeny, curly hair only.

This represents the Mendel’s Law of dominance which is also the Mendel Third Law which states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive.

So, the correct option is ‘Both are homozygous'.

Why do greenstick fractures commonly occur in children? Their bones contain higher amounts of collagen. Their bones contain high
Alisiya [41]

Answer:

This traumatic pathology occurs in children because the concentration of minerals is lower in children, since these have a greater collagen fibrillar organic structure, which is what gives children greater elasticity during bone growth until the areas close. proliferative.

The denomination in green stem comes from the analogy between this type of fracture and the one that occurs when trying to break the green stem of a plant.

It is characterized by being an incomplete fracture, with rupture of the periosteum and cortical bone on the convex side of the bone, while in the concave area the periosteum does not break, as a consequence the bone is not completely broken (incomplete fracture), but the fragments move and present an angulation of variable amplitude that needs to be corrected

Explanation:

To be more specific, these fractures occur more up to ten years of age, according to some research.

The centers of bone proliferation and differentiation where osteochondral mineralization of long bones occurs is what confers greater flexibility and greater organic content in the long bones of children.
