WebSome researchers claim that sponge genomes have homeotic genes, but no Hox genes. If true, this finding would Select one: strengthen sponges' evolutionary ties to the Eumetazoa mean that extinct sponges must have been the last common ancestor of animals and fungi require sponges to be reclassified as choanoflagellates WebAs we’ve already described, there are four general stages in early animal development: Fertilization: the process of a single sperm cell combining with single egg cell to form a zygote. Cleavage: rapid, multiple rounds of mitotic cell division where the overall size of the embryo does not increase. csm leasing

WebThe term "Mox genes applies to clusters of homeotic gonas found in many different animals, including fruit flies. After segmentation ons have established the body segments, Hox genes trigger the development of segment-specific body structures in the correct locations. WebExplanation: Homeobox genes are crucial for very early embryonic development and are involved in cell differentiation and general body pattern. They are similar in eukaryotic organisms because every organism needs these essential functions, such … WebNeil Shubin and Sean Carroll discuss homeobox genes, a set of genes that produce basic body parts in all animals.
