Arecent study found that at least 180 different genes seem to be correlated with height in humans, which is partly why height is a continuous trait. if we imagine a much simpler scenario in which only 10 genes control height, and each of these genes displays simple mendelian inheritance (i. e., there are only two alleles, tall and short, and tall is dominant to short) and shows equal contribution to height, how many different possible genetic height phenotypes would there be in humans?

If the genes show the simple Mendelian Inheritance then the resulting phenotypes would have two outcomes; either a tall height or a short height.

Explanation:

All the 10 genes would carry the same kind of alleles i.e short or tall. So the phenotypes would have only two simple outcomes; either a tall height or a short height

If a dominant and a recessive allele is present in a gamete, then the dominant allele would mask the effect of the recessive allele. Short height would only be seen if both the alleles in the gametes would be recessive.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
