Genes are made up of $DNA$. The genes present in an organism show a particular trait by way of forming certain product. This is facilitated by the process of transcription and translation (according to central dogma of genetics).

Heterozygous purple flower is crossed with recessive white flower. The progeny has the ratio
Match List $I$ with List $II$
List $I$ | List $II$ |
$A$. Two or more alternative forms of a gene |
$I$. Backcross |
$B$. Cross of $F_1$ progeny with homozygous recessive parents | $II$. ploidy |
$C$. Cross of $F_1$ progeny with any of the parents | $III$. Allele |
$D$. Number of chromosome sets in plant | $IV$. Test cross |
