Question

When a plant heterozygous for tallness is selfed, the F${}_2$ generation has both tall and dwarf plants. This proves the principle of

• A. Dominance
• B. Segregation
• C. Independent assortment
• D. Incomplete dominance

Answer 1

The correct option is B Segregation

Law of segregation states that alleles for genes segregate from each other whether it is for tall (TT) or dwarf (tt) so that the gamete carries one allele for each gene, whereas law of dominance states that the phenotype which is expressed is the dominant character and other is recessive, since there are both tall & dwarf plants, this means that both characters are expressed .

So, the correct answer is "Segregation".
