This arrangement means that it is the male that determines the sex of the offspring when fertilization occurs. The first 22 pairs are called autosomes. Featured Content. If the regulatory DNA sequence allows the main sequence to be expressed, the male-trait will appear in the phenotype , otherwise not.
If it occurs before sex chromosomes become heteromorphic, as is likely in the octoploid red sorrel Rumex acetosella , sex is determined in a single XY system. Allosomes not only carry the genes that determine male and female traits, but also those for some other characteristics as well.
