A woman is heterozygous for a recessive allele that causes X-linked hemophilia. This recessive allele has a mutation that makes a gene for a blood-clotting factor nonfunctional. Considering the implications of X-inactivation, the level of clotting factor in her blood is likely to be approximately that of a homozygous non-mutant woman.

Option- 1/2 ( half chances).

Explanation:

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
