Question

Answer

Answer

A woman has  albinism father it means that  she must be carrier for the trait .also , she marries albinic man . It means,,,        X¤X   ×X¤Y  so on crossing  there will  be  half progenies as  normal   and remaining  having disease....

Answer

Explanation:

Genetics of Albinism:
- Albinism is a recessive genetic disorder, meaning that it requires two copies of the gene for albinism to be expressed.
- Individuals with one copy of the gene are carriers and do not exhibit the albino phenotype.

Genotype of the Woman:
- The woman has an albino father, which means she must carry one copy of the albino gene.
- When she marries an albino man who also carries two copies of the albino gene, the possible genotypes for their offspring are:
- NN (normal)
- Nn (carrier)
- nn (albino)

Punnett Square:
- When we cross an Nn carrier with an nn albino, the Punnett square will show the following possibilities:
- 50% chance of NN (normal)
- 50% chance of Nn (carrier)

Proportion of Progeny:
- Therefore, the proportion of her progeny will be 1 normal : 1 albinic, as there is an equal chance of having a normal offspring or a carrier offspring.
Therefore, the correct answer is option 'D' - 1 normal : 1 albinic.
