I mean not exactly 100% resemblence of our parents. Our chromosomes will get changed by means of a process called "CROSSING OVER" and produce new set of chromosomes in our body. Tats why we dont exactly resemble the same as our parents . Its called Variation . Some would have said your eyes look like your mothers and your nose like your fathers. This is due to Heredity. Now coming to your question. The answer is in reference to mendels law. take for example his pea plant experiment. chromosome 1: T ( fathers) chromosome 2: T ( mothers) where T is factor for Tallness( height of yours) here TT see both are similar. so we can represent any one gene. Now again chromosome 1: T (fathers) chromosome 2 : t ( mothers) where T tallness and t dwarfness eventhough Tt the gene t have its character for height( Tall/drawf... both are related to height) so only one gene expresses by transcription and translation and here its T and t wont undergo and such process. similar for tt . Hope this might help you . I have tried hard to explain if its not clear please ask me or if you could tell your views . its welcome my mail: sureshrec22@gmail.com wed: http://sureshtcs005.wordpress.com Hi Khoi,
I am an Biotech student and I can answer your question..
your question is we have 23 ( 1 set ) from our father and 23 ( 2nd set) from our mother. so why you call as 23 and not as 46.

my answer: however eventhough we get 23 set from father and other 23 from our mother we have its MODIFIED FORM of chromosomes in our body.
I mean not exactly 100% resemblence of our parents. Our chromosomes will get changed by means of a process called “CROSSING OVER” and produce new set of chromosomes in our body.
Tats why we dont exactly resemble the same as our parents . Its called Variation . Some would have said your eyes look like your mothers and your nose like your fathers. This is due to Heredity.
Now coming to your question.

The answer is in reference to mendels law.

take for example his pea plant experiment.
chromosome 1: T ( fathers) chromosome 2: T ( mothers)
where T is factor for Tallness( height of yours)
here TT see both are similar. so we can represent any one gene.

Now again
chromosome 1: T (fathers) chromosome 2 : t ( mothers)
where T tallness and t dwarfness
eventhough Tt the gene t have its character for height( Tall/drawf… both are related to height)
so only one gene expresses by transcription and translation and here its T and t wont undergo and such process.

similar for tt .

Hope this might help you . I have tried hard to explain if its not clear please
ask me or if you could tell your views . its welcome

This is basic high school biology. We have 23 pairs of chromosomes. The key word there being "pairs" - one set from our mom and one set from our dad. So why did they choose the number 23 and not 46? If you were scanning someone's DNA, wouldn't it make sense to suggest that you scan the whole thing and not just half of it? So why the name 23 and Me? This is basic high school biology.
