Endocrine gland - a group of cells that secretes substances into the blood or directly into an organ. Differ from exocrine glands, endocrine glands have no ducts and secrete products (hormones) directly into blood.  

Hormone - a substance produced by cells that helps specific groups of cells to perform specific functions. It is a product of endocrine gland which functions as chemical messengers to stimulate other cells.  

Duct – a channel or tube that conveys a substance.  It is part of the exocrine glands (such as salivary glands) which makes contact with surface .

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d). A pigment-eye
Ivenika [448]

Answer:

PpDD and PpDd

Explanation:

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d).

The <u>possible genotypes of a pigment-eyed, dimple-chinned person</u> would be  PPDD, PpDd, PPDd, PpDD while a blue-eyed person without a dimpled chin would have the genotype ppdd.

The genotype of a blue-eyed, dimpled chin child would be either of ppDd or ppDD, but in this case, the mother is ppdd and as such, the child cannot have two copies of D allele. Hence, the genotype of the child can only be ppDd.

In order for the child to have blue eyes (pp), it means that the father has to have the non-pigmented allele (p). This also means that the father is heterozygous for eye pigmentation (Pp).

<em>Hence, the genotype of the father is now limited to </em><em>PpDD</em> <em>and </em><em>PpDd</em>.
