Which of the following statements about a gene that shows maternal effect inheritance is true?
A
The phenotype of the offspring is determined by the genotype of the mother.
B
The phenotype of the offspring is determined by the genotype of both parents equally.
C
The phenotype of the offspring is determined by the environment rather than genetics.
D
The phenotype of the offspring is determined by the genotype of the father.
Verified step by step guidance1
Understand the concept of maternal effect inheritance: In this type of inheritance, the phenotype of the offspring is determined by the genotype of the mother, not the offspring's own genotype.
Recognize that maternal effect genes are expressed in the mother and the products (such as proteins or RNAs) are deposited into the egg, influencing early development.
Consider the options given: The correct statement should reflect the influence of the mother's genotype on the offspring's phenotype.
Eliminate options that suggest the phenotype is determined by the genotype of both parents equally, the environment, or the father's genotype, as these do not align with maternal effect inheritance.
Conclude that the correct statement is: 'The phenotype of the offspring is determined by the genotype of the mother.'
