Homework Answers
Answer- E. All of the above are true.
Reason -
- They appear much more frequent in males vs females. This is because, males have one copy of the X chromosome, so, if they have diseased allele then it will be expressed. In case of females, they have two copies of the X chromosome and if one copy is affected then the diseased will not express, as two copies of the diseased allele are required for the individual to be diseased.
- Females are carriers because to be diseased, they need to have two copies of the diseased X chromosome.
- Affected males can pass the gene to their daughters, but they are usually unaffected. This is because for daughters to be affected they must get a diseased X chromosome from their mother and if daughters get a normal X chromosome from mother then they are unaffected.
Please give a thumbs up!!!!!!!! Ask any doubts regarding the above question in the comment section !!!!!!!!!!! Thank you!!!!!

Look carefully at the pedigrees below and:
1) indicate whether the transmission appears autosomal or
sex-linked
2) indicate whether the transmission appears dominant or
recessive
3) provide at least two characteristics for each that support
your conclusion.

7.) Haemophilia is an X-linked recessive disorder. If a male haemophiliac mates with a normal (non-haemophiliac) homozygous woman, would the progeny be affected? a. All males would be carriers.

10. Red green colorblindness is an X-linked recessive disease. That means that it is carried on the X chromosome, so men have just one copy of the gene while women have two. In women, both copies must be the recessive disease allele in order to show the disease phenotype, but because men only have one allele, just one recessive allele causes the disease phenotype. Matt and Kate both have normal vision, but Kate's father is colorblind. Use X for the...
