Answer:
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.
The correct answer is D...9.8 meters per second squared.
Hello, sorry this is a little late.
I believe the correct answer to your question, "an animals long period of inactivity during winter is called what" would be Hibernation.
Hibernation is when some animals (examples would be bears, and wild rabbits) sleep throughout the entire season of winter, when the temperature is too cold for them. They spend time before hibernation usually stocking up food, and creating a warm place for them to stay.
Hope this helps, and have a great day! :)
