Genetics is the branch of science that deals with the study of gene and their inheritance from one generation to the next generation. Gregor Mendel is known as the father of genetics as he discovered the fundamental unit of inheritance, called a gene. An allele is another important term used in genetics, alleles are the alternative form of the gene. According to Mendelian genetics, allele can be dominant or recessive. The dominant allele is represented by a capital letter while the recessive allele is represented by a small letter. A dominant allele is responsible for the expression of the characteristics in the individual. The recessive allele can express themselves only if both copies of recessive alleles are present which means in the presence of the dominant allele recessive cannot express their genotype as the dominant allele mask their expression. The word genotype is referred to as the genetic makeup of an individual. Genetic make means what kind of alleles the individual possesses. Depending upon the presence of particular alleles an individual can be dominant (Homozygous dominant or heterozygous dominant) or recessive (homozygous recessive). For example, AA (Homozygous dominant), Aa (Heterozygote dominant), or aa (homozygous recessive). The phenotype can be defined as the physical appearance or the observable traits of an individual resulting from their genetic makeup. For example, the white flower, round seeds, curly hairs are examples of phenotype. In the given question, the allele 'R' is dominant for trait Round seeds. Therefore the allele 'r' must be recessive for trait wrinkled seeds. In the same way, as allele 'P' is dominant for trait Purple flower, the other allele 'p' is recessive for trait white flower. As we know, a dominant allele is responsible for the expression of the phenotype in the individual. therefore here the dominant allele 'R' will mask the expression of recessive allele 'r'. Therefore, the phenotype of, RR : Round seeds [ As both dominant alleles are present in this genotype] Rr : Round seeds [As the dominant allele R is present in the genotype it will mask the expression of recessive allele 'r' and show phenotype round seeds.] rr : Wrinkled seeds [As both recessive alleles are present, the recessive allele 'r' will show recessive phenotype i.e. wrinkled seeds.] In the same way, as the allele 'P' is dominant for trait Purple flower, the dominant allele 'P' will mask the expression of recessive allele 'p'. Therefore the phenotype of, PP : Purple flowers [ As both dominant alleles are present in this genotype] Pp : Purple flowers [As the dominant allele P is present in this genotype, it will mask the expression of recessive allele 'p' and show dominant phenotype purple flowers.] pp : White flowers [As both recessive alleles are present, the recessive allele 'p' will show recessive phenotype i.e. white flowers.]
