Which of the following would have the same base sequencing in their DNA?

Question

A. A male parent and his male offspring

B. Siblings

C. Identical twins

D. A female parent and her offspring

Answer 1

identical twins. because they originated from the same egg and sperm.

a mother/father and offspring cannot have same dna sequencing because the offspring's dna resulted from the combination of the dna's of the two parents.

siblings too have diff dna sequences because the combination produced by their parents' dna are different in all them.

Answer 2

actually the dna sequences are affected bt some phenotypic traits like the environment and also mutations which may be dominant or reccessive.
if mutations are recessive they are harmful.
so mutations and environment change sequences during lifetime.
for ur ques the answer is definately identical twins becoz
THEY ARE MONOZYGOTIC.
so their dna sequences are same and yet they are not alike.
it will be clear from following example:
"""The best way to see these effects is to look at identical twins. Identical twins have the same DNA but are certainly not exactly alike. One of the reasons is that as they age, these twins start using their DNA differently.

In one twin, gene A may be going full blast while in the other, gene A is barely on. The bases are the same, they still have an identical DNA sequence.

The difference is that they are using their genes differently—their “dimmer switches” are set to different levels. Same DNA, different people. """

Answer 3

If you mean the whole DNA, then the answer is none. But...
A. A male parent inherits his Y chromosome to his male offspring, so the DNA sequencing in both Y chromosomes would be the same.
B. Siblings have identical mitochondrial DNA, inherited directly from their mother.
C. Identical twins have identical nuclear DNA, but their mitochondrial DNA could be slightly different. Essentially, they do have the same DNA, and it would be nearly identical.
D. A female parent and her offspring would have identical mitochondrial DNA, because all extranuclear inheritance (DNA in mitochondria and chloroplasts in plants) is transmitted directly from mother to offspring.

Good question, it depends on how you look at it.

Answer 4

Actually, none of them have the same DNA sequence. Mutations occur differentially and independently in the embryos.

Still, if you HAVE to choose an answer, it's C.

As said above, it can't be A or D, since parents share only 1/2 their DNA with the children in sexual reproduction. And that half isn't even the same sequence, either, thanks to homologous recombination in meiosis I (when homologous chromosomes switch some alleles).
Siblings are the most closely related of A, B and D. They got their genes from the same source. But you can rule this one out by simple reasoning: do all siblings look exactly alike?

Answer 5

C Identical twins

Answer 6

The answer is c since identical twins are formed by the female gamete splitting to form two genetically identical cells (identical twins)

Answer 7

C. would be the best possible answer. However even identical twins do not have their DNA completely identical.

Answer 8

c, Identical twins share the same DNA

Answer 9

C. identical twins

Answer 10

definitely C 100% they came from the same ovum which splits when it has been fertilised . so definatly C
