Q. Consider the following four statements I, II, III and IV and select the correct statements I. Mendelian experiments has a large sampling size, which gave greater credibility to the data that he collected II. Recessive allele influences the appearance of the phenotype even in the presence of a dominant allele III. Multiple alleles can be found only when population studies are made IV. In $F_{2}$-generation of a Mendelian monohybrid cross, the tall and dwarf traits were identical to their parental types and shows blending inheritance The correct statements are
A) I and III
B) III and IV
C) II and IV
D) II and III
Explanation
Recessive alleles influence the appearance of the phenotype only when they are in homozygous condition. Mendel did not find the blending inheritance in F2-generation of a Mendelian monohybrid cross the tall and dwarf traits were identical to their parental types and doesn’t show blending
