B. $$\frac{{{\text{n}}\left( {{\text{n}} - 1} \right)\left( {{\text{n}} - 2} \right)}}{8}$$
C. $$\frac{{{\text{n}}\left( {{\text{n}} - 1} \right)\left( {{\text{n}} - 2} \right)\left( {{\text{n}} - 3} \right)}}{8}$$
D. $$\frac{{{\text{n}}\left( {{\text{n}} + 1} \right)\left( {{\text{n}} + 2} \right)}}{4}$$
Answer: Option A
Solution (By Examveda Team)
The number of single crosses will be equal to $$\frac{{{\text{n}}\left( {{\text{n}} - 1} \right)}}{2}.$$The term "single cross" means the first-generation hybrid between two inbred lines.
The type of hybrid that is produced when two different inbreds are cross-pollinated, which is also known as an F1 hybrid, are inbreds. Each seed produced from crossing two inbreds has an array (collection) of alleles from each parent.
