Can a girl have genes from her grandpa?

Question

or would it be impossible because his genes would only be passed through the y chromosome to his son? Then the X that the dad gives to his daughter would just be the X from her grandma (that was passed on).

If that makes sense! Thnx.

Answer 1

Most of your DNA is autosomal.  You get it

50-50 from both parents coming down from all your ancestors.  

Y & Mitochondrial are used in genealogy as they go back in a straight  line and remain virtually unchanged.  But it is a minute part of your total DNA

If you get back to you 6xgreat grandparents, barring any duplicates, you are directly descended from 510 individuals.

Of those 510 individuals, you get your mitochondrial DNA from only 8 and if you are a male you get your Y dna from only 8, but you get your autosomal DNA from all 510.

Autosomal determines mostly your physical characteristics such as height  and body build and pigmentation.  I have a bone structure anomaly in my left foot.   I have very high arches and in my left foot I have an additional bone which causes poor support at the arch.  I got that from my maternal grandfather.  My sister's granddaughter had the same anomaly in her right foot until she had surgery.  It skipped 3 generations.  My mother didn't have it and my sister and my nephew have flat feet like my father.

Answer 2

You have 46 chromosomes.  One of them is the Y chromosome which is what boys have, while girls have an X-chromosome there instead (they both have another X-chromosome too).  So girls have two X-chromosomes and boys have one Y and one X-chromosome.

The girl does NOT get the Y-chromosome from the grandpa so in that sense you are right.  A girl gets one X from her mother and one X from her father; the mother's could have come from the mother's father or mother; the one from the father comes from his mother.

So what about a  girl's father's father?  (The grandpa, but just on your father's side).  Does this mean she has none of his DNA?

Actually this is kind of true but for those two X-chromosomes only.  Forty-four more chromosomes come 1/4 from each grandparent as an average estimate; it is EXTREMELY EXTREMELY rare to get 0 chromosomes or DNA from him.  (1in 4 million about chance)

Your mtDNA which is left over, is thought (perhaps questionably) to be purely transmitted from a mother to child, thus in a maternal line.

Answer 3

I think you can get genes from all of your grandparents. My daughter has some of my father's facial charachteristics.

Answer 4

You can and do share the genetic material from your grandfather. In fact you can have gene characteristics from any one in your lineage.

and men pass down x chromosomes, thats how you became a girl. if  they were to pass a y you would have been a boy.
