what is the probabilitym that both recessive genes will be contributed to the child for a specific trait(both parent are heterozygous)

There is a 50% chance that the father will contribute a recessive allele to his offspring if he is heterozygous.
There is a 50% chance that the mother will contribute a recessive allele to her offspring if she is heterozygous.
The probability of the offspring receiving a recessive allele from BOTH the father and the mother is calculated by mutliplying the probabilities of the 2 independent events.
(50%) X (50%) = (25%)
So 25%

25%....is the probability, but not always the reality...I have 3 children, 2 have a genetic (recessive) disability. But the correct answer when considering probabilty is 1 of 4.

Somewhere between 0 to 100% chance .

you should learn to use the punnet square. that will help you figure out the probability. off the top of my head i think 25% is correct.

hm, i wouldnt know the statistics or the probability of it, but i just see it as a 50% - 50% thing...
you just dont know....
