Two heterozygous parents are crossed. If the two loci are linked what would be the distribution of phenotypic features in $F_{1}$ generation for a dibybrid cross?

Solution

Linked loci do not exhibit cross over and therefore; no recombinant gametes will be formed. The cross between two heterozygous parents with linked loci will form gametes with parental genetic combinations only. Fusion of these parental gametes will give progeny having the parental phenotype. For example, a cross between TtRr and TtRr where loci for two genes are linked, both parents will form gametes with parental genetic combinations (TR and tr). Fusion of these gametes will give TtRr progeny (parental type).
