11/14 Genetics

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism's genome.

Front

What are the two types of mutations based on their effects on fitness?

Back

Good mutations (beneficial) and bad mutations (harmful).

Front

What is the difference between a genotype and a phenotype?

Back

A genotype is the genetic makeup of an organism, while a phenotype is the observable physical or biochemical characteristics of that organism.

Front

What is a dominant allele?

Back

A dominant allele is an allele that is expressed in both homozygous and heterozygous states and is stronger than a recessive allele.

Front

What is a recessive allele?

Back

A recessive allele is an allele that is only expressed in a homozygous state and is masked by a dominant allele.

Front

What is the significance of malaria resistance in genetics?

Back

Malaria resistance is considered a good mutation because it provides a survival advantage in malaria-endemic regions.

Front

How can mutations be classified?

Back

Mutations can be classified as beneficial, harmful, or neutral based on their effects on the organism's fitness.

Front

What is the role of alleles in genetics?

Back

Alleles are different versions of a gene that can produce variations in traits.

Front

What is the concept of natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the relationship between mutations and evolution?

Back

Mutations provide the genetic variation that is essential for evolution, as they can lead to new traits that may be subject to natural selection.
