Arlo carries a gene for tallness, but he is fully-grown and only 5 feet tall. tallness is his shortness is his ) phenotype; genotype. b) polygenic inheritance; genotype. c) genotype; phenotype. d) sex-linked gene; expressed gene.

A) polygenic inheritance; genotype

Explanation: Polygenic inheritance is a type of inheritance not attributed to gene dorminance in the case of Arlo, who has a dorminant gene for tallness ànd later didn't become tall. Polygenic traits do not completely follow Mendel's law of inheritance,they can be influenced by other factors such as the environment.

Genotype is the entire genetic make-up of an organism that influences the overall organism.

Unlike phenotype that completely follows Mendel's law of inheritance.
