Which of the following trait shows transmission from carrier female to male progeny?
1 Autosomal dominant
2 X - linked recessive
3 Y - linked recessive
4 X - linked dominant
Explanation:
This is known as crisscross inheritance, when character/traits pass from mother to son and father to daughter.

A colourblind man has a colourblind sister but a normal brother then phenotype of its parents is
1 Father and mother both are normal
2 Father and mother both are colourblind
3 Father colour blind and mother carrier
4 Father colourblind and mother normal
Explanation:
If a female is suffering from an X- linked disorder , than the mother is carrier and father is affected.

Both male and female have normal vision though their fathers were colour blind, and mothers did not have any gene for colour blindness. The probability of their daughter becoming colour blind is:
1 \(0 \%\)
2 \(15 \%\)
3 \(25 \%\)
4 \(50 \%\)
Explanation:
The male's father was colour blind with genotype and mother had no gene for colour blindness with genotype XX, thus genotype of male would be \(X^{c} Y \times X X\) \(\mathrm{XY}\) The female's father was also colour blind with genotype \(X^{c} Y\) and mother had no gene for colour blindness, thus with genotype XX, thus genotype of female would be \(X^{c} Y \times X X\) \(X X^{c}\) On crossing this male and female: \(X Y \times X^{c} X\) Their daughter can have genotype XX or \({\rm{X}}{{\rm{X}}^{\rm{c}}}\), thus she could be normal or carrier, but the probability of she being colour blind is \(0 \%\).

A normal woman whose father was colourblind, is married to a normal man. The sons would be
1 75% colourblind
2 All normal
3 50% colourblind
4 All colourblind
Explanation:
As the woman is carrier of colour blindness so 50% of the sons would be colourblind. [X-linked Recessive].
