There's a great picture that I attached below that is a great representation
Only the birds with the largest of beaks are able to eat the toughest, biggest, and spine covered seeds. Which is not right because some other Galapagos Birds might have some other way eat those seeds with their finches
Explanation:
As we know that different versions of the gene are called as the alleles. Allele is the various sequence of DNA (deoxyribonucleic acid) or alleles are known to be different forms of the genes, which can be seen at the same locus on the homologous chromosomes. Let us know assume that gene Tyx has two alleles in it, which represents the two forms of expression having same character. i.e. Tallness and Dwarfness TT(tall), Tt(tall), tt(dwarf). In the given question, the version
(a) TT, where alleles exist in the homozygous dominant conditions,
(b) Tt, where alleles exist in the heterozygous dominant condition
(c) tt, where alleles exist in homozygous recessive condition. Therefore, it might follow autosomal dominant inheritance, or autosomal recessive inheritance or incomplete dominance etc.
