The sebaceous glands are holocrine glands that produce sebum, a semiliquid mixture of glandular cell debris containing glycerides, free fatty acids, wax esters, squalene, cholesterol, and cholesterol esters. The largest and most numerous sebaceous glands are found on the face, scalp, chest, and back.
Fasciae are layers of connective tissue, mainly collagen, situated under the skin, which closes, supports, and separates muscles and other structures. Fasciae are grouped by their anatomical location, layer (as visceral fascia, superficial fascia, and deep fascia), or by their functions. Fasciae reduces friction and provide an adjustable covering for nerves and blood vessels as they move through muscles.
As we can see in the pedigree, both of the parents do not possess the trait, but one of the four offspring (marked with red) is expressing the trait.
Since the trait is recessive, the only way that is possible that the parents who do not possess the trait to have the offspring with the trait is that the parents are heterozygous for the trait. Meaning that both of the parents have one dominant allele and one recessive allele.
