Answer:
A dog's body grows a tail and fur as part of its natural development process that is encoded in its DNA. DNA, or deoxyribonucleic acid, is the genetic material that contains instructions for the growth, development, and function of all living organisms. The specific instructions for growing a tail and fur are contained in the dog's genes, which are segments of DNA that carry the information for specific traits or characteristics.
Similarly, a bird's body produces a beak and feathers as part of its genetic program encoded in its DNA. Feathers are complex structures that require the expression of many genes in a coordinated manner, and the development of a bird's beak is also regulated by genetic mechanisms.
The scientific term for these features or characteristics is "traits" or "phenotypic traits," which refer to the physical, behavioral, and physiological characteristics of an organism that are determined by its genes.
The instructions for these characteristics are contained in a molecule called DNA, which is composed of four chemical building blocks called nucleotides (adenine, guanine, cytosine, and thymine) that form a double-stranded helix. The specific sequence of nucleotides in an organism's DNA determines its genetic code, which in turn determines the traits that the organism will express.
The organism gets its genetic instructions from its parents through the process of inheritance. When an organism reproduces, it passes on its genes to its offspring, which inherit a combination of genes from both parents. This combination of genes determines the traits that the offspring will express, and the process of inheritance ensures that traits are passed down from generation to generation.
