Different hormones affect different cells’ behavior very effectively in other parts of the body, thus not only affecting the function of the body but the behavior of the animal. As with any online transaction with strangers, do your homework and try to make sure you’re not giving up a good, healthy animal to illegal, immoral, inhumane gambling operations. Thus genes come in pairs, but an individual gene may not do the same as its matching gene. The interesting thing about sex chromosomes is that some genes do not have a matching companion on the other chromosome. Different plants and animals have different numbers of pairs of chromosomes. The only pair of chromosomes that are not identical and thus may not have corresponding pairs of genes are the sex chromosomes.
The sex cells that contain one set of chromosomes are the ova or egg cells of the female and the pollen or sperm cells of the male. However, if the parents are of the opposite arrangement where the rooster is the Plymouth Rock, identifying the sexes by color at hatching is impossible. For example, if one crosses a light Sussex rooster Columbian color pattern to a barred Plymouth Rock hen, one can identify the male chicks from the female chicks at hatching by the cockerel having a distinctly different color marking greyish with a light spot on the head and thus becoming barred as its plumage develops and the pullet being black and staying black as it matures. In birds, it is the other way around where the female has the XY, and the male has the xx.
In humans/mammals, the female sex chromosome pair is xx, and the male is XY. The above is because the gene for barred feathers is only on the “x” sex chromosome and not the ‘y’ sex chromosome, which has a bit missing where the partner to the barring gene should be. The ‘Y’ chromosome has a bit missing; thus, some “X” genes do not have a matching pair in the “XX” male fowl. Sex cells unite to begin a new individual joining one set of chromosomes from each parent and making a new cell with a pair http://220.127.116.11/ of each chromosome, thus a pair of each gene. There are corresponding genes on each of the pairs of chromosomes. The distance to travel, the size of the new destination, the available facilities, cost, and the type of transport, are all influential factors on the number of birds that can logically be moved.
