<u>Answer:</u>
<em>There are equal chances for the second child becoming albino and not becoming albino.</em>
<u>Explanation:</u><u> </u>
Albinism is due to the presence of a recessive gene. <em>Thus every individual should have two copies of this recessive gene in order to be an albino. </em>Recessive genes express only if they occur in pair.
If not the dominant gene trait will be expressed in the organism. Here an albino woman is having children with a normally pigmented man. The cross can be represented as
<em>Let p represent the abnormal pigment gene in albino and P represent the gene for normal pigmentation.</em> The fact that the first child is albino suggests that the genotype of the man is Pp.
Pp Pp pp pp
<em>Here there is equal probability for the child becoming and not becoming albino.Thus the probability that the second child also being albino is ½. </em>
