BIOL2416-41480: Genetics urse Home Chapter 19: Epigenetics Chapter 19-Question 10 Part A Which of the following is an example of genomic imprinting in humans? O A random patterm of autosomal allele inactivation is observed. O Human males have only one Y-chromosome and one X-chromosome Ore of the two X-chromosomes in formales is randomly expressed and the other is repressed. O The maternal and paternal alleles of a gene pair are both expressed In some allele pairs, only the patemal sourced alle is expressod, and in others, only the maternal sourced allele is expressed Submit Request Answer
