The phenotypic ratio of a monohybrid cross in \({F_2}\)-generation is 3:1 ratio A phenotypic ratio of 3/4th tall : (1/4TT + 1/2 Tt) and 1/4th tt, genotypic ratio of 1:2:1.

A test cross is carried out to
1 Determine the genotype of a plant at \({F_2}\)
2 Determine the genotype of a plant at \({F_1}\)
3 Determine the genotype of the parent plant
4 To know if plant will grow / viable phenotype
Explanation:
Therefore, to determine the genotype of a tall plant at \({F_2}\), Mendel crossed the tall plant from \({F_2}\) with a dwarf plant. This he called a test cross.

If a person has one copy of each of two different alleles for a given gene, the person is _______ for that trait.
1 True-breeding
2 Heterozygous
3 Recessive
4 Homozygous
Explanation:
Hetrozygous have different alleles for a gene for a given character.

Smallest structure having the power of replicating itself is
1 Ribosome
2 Gene
3 Chloroplast
4 Mitochondria
Explanation:
A unit of heredity that is transferred from a parent to offspring and is termed as a gene.Being a part of DNA it can replicate

The alleles are
1 Multiple forms of genes
2 Genes present in allosomes
3 Genes governing eye characters
4 A pair of genes governing a specific character such as tallness or dwarfness or alternate form of gene.
Explanation:
alleles are the alternative forms of the same character, which produce different effects. They also occupy same position on the homologous chromosomes. For example; tall and dwarf plants are contrasting alleles representing the same character i.e., height of pea plant
