A Y linked gene ___________________(a) Is expressed only when homozygo

1.	A Y linked gene ___________________(a) Is expressed only when homozygous(b) Is present near the telomere of long arm in human(c) Is carried by mother(d) Expressed only in menI got this question during an interview.Asked question is from Sex Linked Inheritance in section Chromosomes and Sex Determination of Cytogenetics
Answer» Right option is (d) EXPRESSED only in MEN Easy explanation: A Y linked gene is expressed only in men and never in females as females lack a Y chromosome. It is not expressed in homozygous, rather in hemizygous for as its present only in a SINGLE copy. The REGION near that telomere is common for both sex chromosomes, so it is not sex linked.
