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).

Chromosomes are molecules that consist of a very long strand of DNA coiled many times, and a few proteins called histones which hold the whole structure together. To put things very simply, chromosomes are made up of genes and genes are made of DNA. gene is a section of the DNA that codes for something, like hair color. DNA is a double helix of nucleic acids. DNA twists and folds to create a structure called a chromosome. Source(s): B.S. in Neurobiology.
