The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

In the case of Bobtail cats, the gene for the tail length follows simple Mendelian inheritance. The allele for a normal tail (T) is dominant, while the allele for a Bobtail (t) is recessive. This means that an individual must inherit two copies of the recessive allele (tt) to have a Bobtail. If they inherit one or two copies of the dominant allele (T), they will have a normal tail.<\/p>\n\n\n\n

Here are the genotypes and their corresponding phenotypes:<\/p>\n\n\n\n

    \n
  1. TT<\/strong>: This genotype consists of two dominant alleles for normal tail length. Since the dominant allele T masks the effect of the recessive allele t, a cat with the TT genotype will have a normal tail<\/strong>. There is no possibility for a Bobtail phenotype because the presence of two dominant alleles overrides any potential recessive traits.<\/li>\n\n\n\n
  2. Tt<\/strong>: In this genotype, the cat has one dominant allele (T) and one recessive allele (t). The dominant allele T will determine the phenotype, meaning that the cat will also have a normal tail<\/strong>. The recessive t allele is still present, but it does not affect the phenotype unless the cat inherits two copies of the t allele (tt).<\/li>\n\n\n\n
  3. tt<\/strong>: This genotype consists of two recessive alleles for Bobtail. Since there are no dominant T alleles present to override the recessive t alleles, the cat will have a Bobtail<\/strong>. This is the only genotype in which the recessive Bobtail phenotype is expressed, as the recessive alleles need to be homozygous (tt) to show their effect.<\/li>\n<\/ol>\n\n\n\n

    In summary, the phenotype of the cat is determined by the interaction between the dominant and recessive alleles. A TT or Tt genotype results in a normal tail because the dominant T allele masks the effect of the t allele. A tt genotype, however, results in a Bobtail because both alleles are recessive and the dominant T allele is absent. Thus, only a homozygous recessive (tt) genotype can produce a Bobtail phenotype.<\/p>\n\n\n\n
