In Drosophila melanogaster, cinnabar eye (cn)and vestigial wing (vg) are simple recessive traits.a A male pure line wild type eye ,vestigial wing cross with female pure line cinnabar eye, wild type wing . F1female, heterozygous for both genes, was crossed with a male with cinnabar eyes and vestigial wings. The offspring resulting from this cross are listed in below class

I Wild type

II Cinnabar eye, wild-type wing

III Wild-type eye, vestigial wing

IV Cinnabar eye, vestigial wing

Above class are recombinant progeny

Chemical regulation of stem cells takes the form of secreted proteins from surrounding cells that influence stem cell states and progenitor differentiation through endocrine, paracrine, or juxtacrine mechanisms. These signaling factors:

In drosophila, the somatic cells of the hub are able to regulate stem cell proliferation by secreting the paracrine factor Unpaired onto the cells attached to them. Unpaired activates the JAK-STAT pathway in the adjacent germ stem cells to specify their self-renewal. Those cells that are distant from the paracrine factor cannot receive this signal, they begin their differentiation into the sperm cell lineage. This means hub cells act as
