A bird will go broody whether or not you have a rooster. Some breeds will even go broody whether or not they have eggs; I have a Nankin hen who, in the absence of eggs, will gather small stones and set on them instead. I had someone call me once and ask me for a broody hen.
The DNA in a person is a combination of the DNA from each of their parents. Part of an organism's DNA is  non-coding DNA  sequences. They do not code for protein sequences. Some noncoding DNA is transcribed into non-coding RNA molecules, such as transfer RNA, ribosomal RNA, and regulatory RNAs).Other sequences are not transcribed at all, or give rise to RNA of unknown function. The amount of non-coding DNA varies greatly among species.ome noncoding DNA is transcribed into non-coding RNA molecules, such as transfer RNA, ribosomal RNA, and regulatory RNAs).

The DNA is compacted into lengths called chromosomes by interacting with histones and other proteins. DNA is mainly localized to nucleus as well as mitochondria and chloroplasts. When DNA mutates, a disease or other abnormality may result. A mutation is a change in the base sequence of DNA. A protein is made of amino acids. DNA consists of two sugar-phosphate backbones, spiraling around each other in a double helix, and joined to each other along their lengths by base-pairs. The base-pairs are adenine with thymine, and cytosine with guanine; none of these are amino acids.
