The statement 'she has at least one recessive color blindness allele' must be TRUE about the mother (Option A).

What is chromosome X inheritance?

Chromosome X is a special type of chromosome whose inheritance pattern is different from Mendelian inheritance.

  • Males receive only one X chromosome, whereas females receive two X chromosomes.

  • A carrier is an individual who inherits one defective allele (in this case, the color-blindness allele).

In conclusion, the statement 'she has at least one recessive color blindness allele' must be TRUE about the mother (Option A).
