    Two girls of the same father are born 10 years apart. Very different mothers. The girls are adults now and look exactly the same (and not at all like the father). How is this done?

    In fact, one is Muslim and the other a die-hard born again Christian. They look like twins!

    It's probably impossible that 2 step-sisters or even sisters 10 years apart can look exactly the same, barring a disease like the one that causes accelerated aging. They can bear a close resemblance, however.

    I agree with limdi but I can’t convince him, it’s just genetics, a strong gene……...

    OK, here's a thought:   The mothers were sisters, or even identical twin sisters.  Their faiths have no bearing on this!

    never even met. 20 years between them.

    A friend of mine is 20 years younger than her oldest sister. Do you have an article somewhere I can read about it?

    Talk with James. I have the pictures on my computer. These are his kids…...

    Can you send me the pix. I would love to see them!

    Will do!

    Mendel’s Laws of Inheritance



    Genetic inheritance boils down to three simple concepts put forth by Gregor Mendel, a humble monk and part-time scientist who founded the entire discipline of genetics:




    • Segregation: In diploid organisms, chromosome pairs (and their alleles) are separated into individual gametes (eggs or sperm) to transmit genetic information to offspring.




    • Dominance: A dominant allele completely masks the effects of a recessive allele. A dominant allele produces the same phenotype in heterozygotes and in homozygotes.




    • Independent assortment: Alleles on different chromosomes are distributed randomly to individual gametes.>>>http://www.dummies.com/how-to/content/genetics-for-dummies-cheat-sheet.html

    Here it is in black and white but I still can’t convince him…..
