Answer:
Yes, this is true. This is because animals also carry genes which codes for a certain trait, and these traits have their own allele. Mendel's experiment portrayed tall plants and dwarf plants being crossed, moreover the colour of the flowers could also be taken as an example. In the similar way, animals, for example, mice, could be white furred or brown furred. They both carry alleles which codes for their fur colour, like plant alleles which codes for either tall or dwarf.
