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
It’s probably the 1st or the 4th choice but i’d say the 4th
Answer:
It's C.
Explanation:A squared plus b squared equals c squared, then square root the c value to get your answer
So A=18 and B=24 right? But C, the diagonal length of the table is unknown. If we split the table into two triangle instead of a rectangle, the diagonal length becomes a missing side. So now you can do 18^2 + 24^2 = C^2 or 324+576=900 square rooted. or 30.
Lol. Here I am.. Saying whatever the heck I want. :)
