In Mendel's experiments with peas, one single locus was responsible for determining whether a plant would be tall or short. Similarly, different alleles of a single locus in humans, for example the FGFR3 locus, can make a person either exceptionally tall or to be a dwarf. Yet, we know that hundreds of genes are responsible for determining height among the normal population. Briefly explain in your own words why sometimes one locus can explain the difference between very tall/short while at other times it is hundreds of loci that determine height

In Mendel's experiments with peas, one single
locus was responsible for determining whether a
plant would be tall or short. Similarly, different
alleles of a single locus in humans, for example the
FGFR3 locus, can make a person either
exceptionally tall or to be a dwarf. Yet, we know
that hundreds of genes are responsible for
determining height among the normal population.
Briefly explain in your own words why sometimes
one locus can explain the difference between very

that determine height
