b) longevity genes; susceptibility genes
c) phenotype; genotype
d) genotype; phenotype
Answer:d) genotype;phenotype
Explanation: Genotype can be defined as the part (DNA sequence) of the genetic makeup of an organism which determines a specific characteristic (phenotype) of that organism.
While the Phenotype is defined as the appearance of an organism based on a multifactorial combination of genetic traits and environmental factors, especially used in pedigrees.
Joseph's genotype is a potential to be tall but due to some circumstances surrounding him, it couldn't be expressed, the Phenotype.
Answer: genotype ; phenotype
Explanation: Analyzing individual's genotype refers to the hereditary composition or what is embedded in the genes of a person. However, the phenotype refers to those attributes or characters in an individual's genetic composition which are observable, they include the traits, character and behavior which could be physically observed or accessed about an individual's hereditary composition. In the context above, Josephbwas supposed to be tall due to the fact that his parent's were, which is the genotype, embedded hereditary information, However, he wasn't as tall as expected due to nutritional constraint, which is the physical or observable trait of Joseph's height, this is the phenotype.
