Answer:
A, pleiotropy.
Explanation:
Pleiotropy - genes that have multiple phenotypic effects. Remember that phenotype means a physical characteristic caused by a gene, such as eye color or fur patterns.
Incomplete dominance - when neither allele is dominant and they mix together in the phenotype. A popular example is a red flower crossing with a white flower and resulting in a pink flower.
Epistasis - when two genes contribute to the phenotype, but one gene completely masks another gene. An example would be labrador fur colors.
Multiple alleles - 3 or more alternative forms of a gene, but only 2 alleles can occupy an organism. An example is blood type.
Hope this helps!
Answer:
1. Mutation
2. Epigenetics
Explanation:
1. Mutation occurs when there is a change in an organism's DNA sequence as a result of mistakes in DNA replication or as a result of environmental factors like smoking. The mutation in a single organism can be passed on to other generations hence causing a genetic variation in the population, this obeys the Darwin's law that inherited traits (genetic) are passed on to other generations
2. Epigenetics are changes in gene expression that doesn't involve changes in the DNA sequences unlike mutation. This changes can be passed on to other generations and hence cause a variation in the population. This obeys the Lamarckian evolution that acquired traits are passed on to other generations.
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
I believe these are the answers:
1. independent variable
2. dependant variable
