Read the following statements regarding Mendelian inheritance and choose the correct option 1. Mendel's experiments had samll sample size which gave greater credibility to the data 2. A true breeding line shows a stable trait inheritance and expression for several generations 3. In a dissimilar pair of factors, one member of the pair dominates over the other 4. A recessive parental trait is expressed only in its heterozygous condition 5. Two alleles of a gene are located on homologous sites on homologus chromosomes

When a wheat variety of red karnels (homozygous for two nonallelic and independent dominant genes) is crossed with white kernelled wheat (homozygous for two recessive nonalleic independent genes), the phenotypic ratin in F_(2) generation would be

When dilute HCI is added to a white substance (A), a colourless gas (B) is evolved. When the gas (B) is passed through clear lime water, a white precipitate ( C) is obtained. The precipitate dissolves when excess of the gas (B) is passed through the lime water. The residue obtained on heating the solid substance (A) is yellow when hot but white when cold. When the gas (B) is passed through red hot charcoal, another gas (D) is obtained. The gas (D) gets absorbed in arnmoniacal cuprous chloride solution . Identify (A), (B), (C) and (D) and give the relevant reactions.

If 'A' represents the dominant gene and 'a' represents its recessive allele, which of the following would be the most likely result in the first generation offspring when Aa is crossed with aa?
