Name the human chromosome that has (a) most number of genes (b) least number of genes

Given below is a sequence of alphabets representing the genes of chromosome. Observe it and answer the questions. A - B - C - D - E - F - G - H - I - J - K . (a) Write the sequence of genes after the chromosome undergoes terminal deletion of single gene. (b) What will be the gene sequence, if the genes E and F undergoes tandem duplication ? (c) Consider the centromere is located between the genes F and G and write a gene sequence , after parametric inversion occurs in between the genes C, D and E.

How many sex chromosomes does a normal human inherit from father?

Name a disorder a human suffers from as a result of monosomy of the sex chromosome. Give the karyotype and write the symptoms.

Aassertion : In humans , most sex-lineked genes are present on the X chromosome. Reason : Human chromosome contains a large number of genes with major effects on phenotype.
