Extra: In an example of polygenic inheritance, there are three genes that control skin appearance in lizards, B, G, and R. B makes bumpy skin, while b is smooth. G provides gridded skin, while g is lined. R is red, while r is green. All are simple

Extra In an example of polygenic inheritance,
there are three genes that control skin
appearance in lizards, B, G, and R. B makes bumpy
skin, while b is smooth. G provides gridded skin,
while g is lined. R is red, while r is green. All
are simple dominant recessive relationships,
except that accumulation of a total of 4 or more
dominant alleles is fatal. For a cross of two
parents heterozygous for all traits, what will be
the chance of bumpy, red and gridded of the
surviving offspring?
