A true Coelom develops completely within the mesoderm. It is also referred to as a body cavity passing down the trunk of some organisms <u>which originates through the splitting of the mesoderm during the initial stages of embryonic and later fits inner to it</u>. Organisms that have a Coelom contain complex structures and are found higher in the taxonomic order. i.e. the Coelomates
The general shape of the epithelial cells that are nearest
to the lumen during an empty urinary bladder of an individual is transitional
cuboidal epithelium, they are cuboidal in shape as they are relaxed and later
transition when stretched and filled with urine.
This is because the Crossing over during meiosis cause is a homologous chromosomes to exchange alleles resulting in new combos of alleles in the offspring. Crossing over occurs between prophase 1 and metaphase 1 and is the process where homologous pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. It can also happen during mitotic division, which may result in loss of heterozygosity.
