Answer:
homozygous recessive
Explanation:
Cystic fibrosis is a recessive genetic disorder. It means that the trait is caused due to the presence of a recessive allele. The recessive alleles are expressed only in homozygous recessive genotypes. Individuals that express the disorder cystic fibrosis should have two copies of a recessive allele of the gene, that is, the genotype should be homozygous recessive.
If "C" allele is the normal healthy allele and "c" allele is cystic fibrosis allele, the genotype of the affected individual would be "cc".
Answer:
First filial generation.
Explanation:
Mendel is known as the father of genetics. He formulated the law of segregation and law of independent assortment by working on the pea plant.
The Mendel first crossed the pure breed line parents and obtained the first filial generation. The F1 generation is obtained by the cross breeding of the parental generation.
Thus, the correct answer is option (D).
