Question
When a silenced allele is inherited from one parent, this is calleda. chromosome inactivationb. imprintingc. development and differentiationd. environmental influencee. maintenance of genome integrity
Step 1
An allele is a variant form of a gene, and it can be either active or silenced. When an allele is silenced, it means that it is not being expressed or functioning. Now, let's consider the options given: a. Chromosome inactivation: Chromosome inactivation refers Show more…

When a gene is inactivated during gamete formation and that gene is maintained in an inactivated state in the somatic cells of offspring, such an inheritance pattern is called a. linkage. b. X-chromosome inactivation. c. epistasis. d. genomic imprinting. e. polygenic inheritance.
Genomic imprinting can be explained by a. DNA methylation of genes during gamete formation. b. epistasis. c. the spreading of $\mathrm{X}$ -chromosome inactivation from the Xic locus. d. the inheritance of alleles that contribute additively to a trait. e. none of the above.
Which of the following is true of genomic imprinting? a. The sex of the parent that transmits an allele affects the expression of the allele in the offspring. b. The sex of the offspring affects the expression of an allele inherited from one of the parents. c. The sex of the parent affects how an allele is transmitted to the offspring. d. The sex of the offspring affects which allele is inherited from the parent
