Answer;
Alleles are passed from the parents’ sex chromosomes to the sex chromosomes in the offspring.
Explanation;
-Sex linked traits are traits that are carried by the sex chromosomes and inherited together.
-Gene exists in alternative forms called alleles and each allele for a trait is inherited from each parent.
-Sex traits, like the other traits, are passed from parents to off spring through the process of sexual reproduction.
This would be a recessive disease.
Father is dd
Mother is Dd (has to be because one child has the disease)
Parents cross is dd x Dd which gives rise to Dd (0.5) and dd (0.5). Each time they have a child they have a 50% chance of the child having the disease. In their case, only one of their 3 children is dd. The others though are carriers!
