<u>Answer</u>: The allele for short pea plants is masked during the F1 generation, but it is still present in the genotype.

<u>Explanation</u>:

  • There are two types of alleles present for a given gene. One allele is the <em>dominant</em> allele and the other is <em>recessive</em>.
  • Whenever a dominant allele is present it is able to <em>mask the expression</em> of the recessive allele. Therefore, whenever a dominant allele and recessive allele are present together (heterozygous condition) the phenotype is that of the dominant allele.
  • Whenever, the phenotype of the recessive allele appears it is necessary that the recessive alleles have to be in homozygous condition.
  • Thus, in the <em>P1</em> generation, the short pea plants are there as there is <em>homozygous condition (tt)</em> and the same happens in the case of<em> F2</em> generation. However, in the <em>F1 generation,</em> all the progenies have the genotype <em>Tt, this is a heterozygous condition</em> and thus, the short pea plants are not seen in F1.
  • Such a condition arises when TT (tall plant) is crossed with tt (short plant) in the P1 generation.
  • The diagram attached shows the punnet square for such a cross and the results of the cross is the F1 generation. As seen from the punnet square all the F1 progenies are of Tt genotype and, the phenotype of tall plants is produced as T (tall) is dominant over t(short) allele.
