Question

what is the primary function of a pedigree chart? a. displaying the occurrence of a particular trait across multiple generations within a family b. explaining the interaction between genotype and phenotype c. representing dominant alleles within a genotype d. displaying the dominance of certain traits over others how does genotype differ from phenotype? a. genotype is inherited, while phenotype is acquired b. genotype refers to dominant traits, while phenotype refers to recessive traits c. genotype is the observable trait, while phenotype is the genetic makeup d. genotype is the genetic makeup, while phenotype is the observable trait which of the following traits is typically associated with sex - linked inheritance? a. color blindness b. height c. blood type d. eye color

Explanation:

1. A pedigree chart is a diagram that shows the occurrence and appearance or phenotypes of a particular gene or organism and its ancestors from one generation to the next. So the primary function is to display the occurrence of a particular trait across multiple generations within a family.
2. Genotype refers to the genetic makeup of an organism, the combination of alleles it has for a particular gene or set of genes. Phenotype is the observable physical or biochemical characteristics of an organism, which is the result of the interaction between its genotype and the environment.
3. Color - blindness is a sex - linked trait. It is carried on the X chromosome. Males are more likely to be color - blind because they have only one X chromosome. Height, blood type, and eye color are not typically sex - linked traits.

Answer:

1. a. Displaying the occurrence of a particular trait across multiple generations within a family
2. d. Genotype is the genetic makeup, while phenotype is the observable trait
3. a. Color blindness
