Contrast penetrance and expressivity as the terms relate to phenotypic expression.
select the two correct statements.
a. expressivity refers to the percentage of individuals that expresses the mutant phenotype.
b. expressivity is the proportion of individuals with a specific genotype who manifest that genotype at the phenotype level.
c. penetrance refers to variations in a phenotype among individuals carrying a particular genotype.
d. expressivity refers to the range of expression of a given phenotype.
e. penetrance refers to the percentage of individuals that expresses the mutant phenotype.
f. penetrance refers to the range of expression of a given phenotype.

d. Expressivity refers to the range of expression of a given phenotype.

e. Penetrance refers to the percentage of individuals that expresses the mutant phenotype.

Explanation:

Penetrance is the probability of a gene being expressed. Sometimes, phenotype is not observed even when the dominant allele is present. It is a result of various genetic and environmental factors coming together.This phenomenon is called as incomplete or reduced penetrance. For example: polydactyly trait is produced by a dominant allele but its penetrance is low in general population hence few people show this trait.

Expressivity is the variation in phenotypic expression when an allele is penetrant. Same genetic combination for a trait can have different expressivity in the same population. This phenomenon is also a result of genetic and environmental factors acting together. For example: people who do end up showing polydactyly trait may show it to different degrees. Some might have one extra finger, some might have two. Some might have a stub, some might have a full grown finger.

no they are not always accurate because they can not give you a specific fortune reading they can not tell you exactly what’s gunna happen

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
