1) recessive allele is b
dominant allele is B
When an X chromosome contains the dominant allele,is written as:

</span><span>When an X chromosome contains the recessive allele, is written as:

</span>
2) the genotype of the woman is
She is not color-blind but she is a carrier of red-green color blindness, who passed the allele to their sons.
