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

Respuesta :

Answer: 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 Ă nd 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.
