Answer / baba_mailme
The multiple effect of a gene is called pleiotropy, and a
gene having multiple effect is called a pleiotropic gene.
In other words a gene that influences more than one trait
is known as pleiotropic gene.
for example, in humans the gene that causes an inborn
disease PHENYLKETONURIA in homozygous recessive stste is
pleiotropic. Its major effect is accumulation of the amino
acid PHENYLALANINE in the tissues that damages the brain
and causes the disease. its secondary effects includes
short stature, excessive sweating, non pigmented hairs and
eyes, pigmented patches on the skin, widely spaced
incisiors.

what is co-dominance ?
Consider two linked autosomal genes. The dominant allele C of the first gene causes cataracts of the eye, whereas its recessive allele produces normal eyes. The dominant allele P causes polydactyly (an extra finger) whereas its allele (p) produces a normal number of fingers. A man with cataracts and normal fingers marries a woman with polydactyly and normal eyes. Their son has both polydactyly and cataracts and he marries a woman with neither trait. What is the probability that their first child will have cataracts and polydactyly?
