Correct option is C

✅ (c) Homozygous and Homogeneous [Pure Lines] • Pedigree selection is used in self-pollinated crops to select desirable homozygous individuals across generations. • The goal is to develop genetically uniform (homogeneous) and homozygous lines. • It is an effective method to fix desirable traits. • Resulting varieties are true-breeding.
❌ (a) Heterozygous and Homogeneous • Heterozygosity implies genetic variation within individuals. • Not possible to be homogeneous (uniform) if individuals are heterozygous.
❌ (b) Heterozygous and Heterogeneous • Indicates variability both within and between plants. • Opposite of the result of pedigree selection.
❌ (d) Homozygous and Heterogeneous • Homozygous individuals, but with differences among them – not the outcome of pedigree selection.
