Signal transduction may result in changes in gene expression and cell function, which may alter phenotype in an embryo. An example is the expression of the SRY gene, which triggers the male sexual development pathway in mammals. This gene is found on the Y chromosome.
Which statement provides the evidence to justify the claim that signal transduction may result in an altered phenotype?
If the SRY gene is absent or nonfunctional, the embryo will exhibit male sexual development.
If the SRY gene is absent or nonfunctional, the embryo will exhibit female sexual development.
An embryo with a male sex chromosome will always exhibit male sexual development.
An embryo with two male sex chromosomes will always exhibit male sexual development.
