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
Answer: The AARP lobbies for the expansion of Medicare to cover more people and provide more services.
Explanation:
President Reagan and indeed most Republicans advocate for more power to be shifted to the State government. This means a reduction in federal influence in areas traditionally controlled by States.
Health is one of those areas so in lobbying the federal government to expand Medicare to cover more people and provide more services, the AARP is asking the FG to extend its control more into state controlled areas which is why President Reagan would most likely oppose it.
