Ahusband and wife have a son with cystic fibrosis. their second child, a daughter, does not. prepare a pedigree for this family

Pedigrees should demonstrate that the parents have an ordinary overwhelming allele and the latent CF allele and in this way are bearers for CF. Their child is homozygous recessive; their little girl has no less than one duplicate of the ordinary predominant allele. 
To have cystic fibrosis the two parents must be a bearer. Each parent passes on one of their qualities to their youngsters; they each have one sound and one cystic fibrosis quality. The youngster with cystic fibrosis gets a cystic fibrosis quality from each parent. The other kid has no less than one sound quality in the event that she doesn't have cystic fibrosis, however she could be a bearer.
Hope it helps!

Dcalifornia they have the most people with 200+ people per square mile
