Myron constructed the pedigree shown below to study the inheritance of a specific trait in his family. A single gene that has tw
o alleles determines whether or not the trait is expressed. In the pedigree, Myron's parents are represented by a circle and square in the top row. The three sons of the parents are represented by squares in the second row. The shaded square represents the son who expresses the trait that Myron is studying.

The pedigree provides the strongest evidence for which of these conclusions?
A. The trait is harmful, and may be a genetic disorder.
B. The allele for the trait is dominant.
C. The allele for the trait is recessive.
D. Only males may express the trait.
The same ligand can bind to different receptors causing different responses (e.g.. acetylcholine). On the other hand, different ligands binding to different receptors can produce the same cellular response (e.g. glucagon, epinephrine).
Answer:I believe it would be A, since that males have two sex-linked genes(which also causes a baby to be either male or female) they have a higher chance of getting a genetic disorder.
Explanation: the male and females sex organs are different
Mitochondria are famed as the energy factories of eukaryotic cells, the seat of an array of membrane-bound molecular machines synthesizing the ATP that powers many cellular processes.
