They come from the same 'place' that all other Living Creatures Genes come from - Three Billion Years of Biological Evolution.
The Sex chromosomes
No, the genes are in the chromosomes
Genes are stretches of DNA that contain code to make proteins. Chromosomes are made up of numerous Genes.
Genes come in pairs because Genes are in chromosomes and chromosomes come in pairs as well.
Chromosomes contain genes, which are the units of inheritance that carry genetic information. Genes are located on specific locations on chromosomes, known as gene loci. Each chromosome carries hundreds to thousands of genes that determine an individual's traits and characteristics.
Humans have 46 chromosomes (23 pairs), chromosomes are long strands of genes, and since the chromosomes come in pairs, so do the genes. There are 25,000 genes in the entire human genome, and since the haploid chromosome number is 23, there are about 100's of genes on the shorter chromosomes and approximately thousands on the longer chromsomes.
Chromosomes are structures that contain genes, which are the functional units of heredity. Genes are specific segments of DNA that encode information for producing proteins, while chromosomes are made up of DNA and protein and contain many genes. Chromosomes are organized in pairs in a cell's nucleus, while genes are the specific units on chromosomes responsible for inherited traits.
Genes are located on chromosomes. Genes are simply regions on chromosomes that code for polypeptides.
The genes carried on the X and Y chromosomes are called your "sex chromosomes".
if a cat has 38 chromosomes in each of its body celss, how many chromosomes will be in each daughter cell after mitosis?
Genes are located on chromosomes and carry hereditary instructions that are passed from parents to offspring. Genes determine various traits and characteristics in living organisms.
Autosomes are identical to each other whereas sex chromosomes come in two forms, X and y and code for the sex linked characteristics (and some other traits) and are the 24th pair, determine sex.
