Question
One of the parents of a cross has mutation in its mitochondria.In that cross;that parent is taken as a male. During segregation of F2 progenies that mutation is found in
Options
A.one-third of the progenies
B.none of the progenies
C.all of the progenies
D.fifty per cent of the progenies
Solution
It is the female reproductive cell which unually carrie more cytoplasm and cytoplasmic or ganelles than the male cell and hence, naturally would be expected to influence non-Mendelian traits. Since in the present case the male parent (not female) had mutation in mitochondria, there are negligible chances of the mutation being inherited.
