Answer:
Option D
Explanation:
Options for the question
A) The Y chromosome is slower to mature than the X chromosome.
B) Replication of the X chromosome occurs more often in males.
C) Male hormones cause the expression of X-linked traits.
D) Males only have one copy of the X chromosome
Given-
Duchenne muscular dystrophy (DMD) is an X-linked recessive condition which means it will occur in male even if they have one diseased X gene. While females will have this disease only when they have two diseased X gene
Hence, in most of the cases women with only one diseased X chromosome act as carrier and show normal traits.
Let us assume X is normal gene and X' is the diseased gene then
Genotype of normal father will be - XY
Genotype of carrier mother will be - XX'
Now if these two mates, following offspring will be produced
XY * XX'
XX, XX', XY, X'Y
So the male with X'Y will have DMD
Hence, option D is correct
Under the terms of the compromise, each state's congressional delegation would be split between representatives, who would be elected by district and serve in the House of Representatives, and senators, who would represent their state in the upper house of Congress. This system struck a balance between the demands of the large states for proportional representation in the Legislative Branch, while addressing the concerns of the less-populous states that their interests would be ignored or overridden by the much larger delegations of big states.
The practical effect created a two-tiered system in which the needs of the people could be addressed in the lower house of Congress, and the competing interests of the states could be handled in an upper house where each state enjoys an equal voice. This split between direct and indirect representation would later influence the formation of the Electoral College and the election of presidents.
