Q. Imagine that on the other side of the wall surrounding Mendel’s garden, he threw left-over seeds.

Consider physiology of peas that he worked with 7 paired traits, that one generation of peas takes one year, and he over his experiments in 1865.

a) How many different combinations of phenotypes could exist of these 7 paired traits?

b) If a pea seed, heterozygous in all 7 loci grows and selfs, what proportion of its seeds will still be heterozygous in every trait?

c) What proportion would be heterozygous in every trait after 2 years?

d) What proportion would be heterozygous in every trait after 139 years?
