racial mixture/dna? recessive and dominant genes?

Question

My mom has a friend and the woman is in her late 40s with a young son in his mid twenties like myself and a young teenage daughter. We have been over their house for get togethers and to hang out and stuff in my younger years. Anyhow, our friend, named Rosie, is Spanish mixed with Indian blood. She has the dark hair, skinand indian features. Her husband is from England and has white skin and blue eyes. Her son was born sometime in 1985(I am four years older and) and the other child 3 years later. We are close friends and so we do know the children are hers biologically. The thing is that the children do not look Indian or mestizo. I mean they are WASP looking like their father. As far as science we know the mestizo gene would be prominent. I am aware that the recesive gene can appear.I guess it is good they look like dad but what if the dad was Indian and the mom was white it migh raise a few eyebrows. How common is it for recessive genes to replace dominant genes?

Answer 1

Interesting question...let's wait for the answers, Shall we??

Answer 2

Rosie probably has dominant and recessive genes. I would guess that she contributed recessive genes for lighter eyes and hair. I have cousins where the kids in one family range from blond hair, blue eyes and white skin to dark skin hair and eyes. That side of the family is Black, French and Cherokee.

Answer 3

you should keep in mind that purely a tiny fraction of alleles and genes artwork contained in the straightforward, classic way that Mendel defined. fairly than putting forward that allele A is dominant, that is fairer to assert that, lower than maximum genetic backgrounds, allele A is punctiliously dominant over allele B. yet when allele C is likewise dominant over allele B, then something might want to take position in an organism with both A and C. perhaps between both is punctiliously dominant over the different. perhaps it relies upon strongly on what alleles are modern-day in different genes. perhaps you get a co-dominant effect. And similar with 2 alleles which take position to be recessive compared to three different allele D. those 2 alleles may be co-dominant to at least one yet another, or you may dominate the different, or perhaps the effect isn't conceivable to foretell, because that is in holding with what's happening in different genes, or our surroundings. It purely relies upon on the precise concern.

Answer 4

thats a hard question. you need a geneticist to answer this one because it depends on what genes both of the parents are carrying. good question though. i'm sure you could do some research on this topic
