Station 6
Parents are Ff and Ff
A. Cystic Fibrosis is a recessive gene (f) on
Chromosome 7 that causes the affected
individual to have abnormal amounts of
mucous. What would be the possible
offspring of two heterozygous parents?
What are the possible genotypes and
percentage of the offspring?
25% FF, 50%, Ff, 25% ff

Parents are cs and ss
Curly type hair (cc) and straight hair (ss)
alleles together will give the phenotype of
