Coelom

Animals with 3 issue layers may be characterized by the presence or absence of a <u>Coelom</u>.

  • Animals may be characterized by the presence of a coelom, formation of the mouth, and type of cell cleavage during embryonic development.
  • Diploblasts contain two germ layers that is the inner endoderm and outer ectoderm, while triploblasts contain three germ layers, that is; endoderm, mesoderm, and ectoderm.

Photopigment genes are located on the X chromosome. Color blindness occurs when an individual has missing or damaged alleles. A
Hunter-Best [27]

The probability that their son exhibits the 'color blind' trait is 0%. It is a type of inheritance linked to the X chromosome.

<h3>Inheritance linked to the X chromosome</h3>

In men, the patterns of inheritance linked to the X chromosome don't follow conventional mendelian inheritance because men have only one X chromosome.

Conversely, women have two X chromosomes, thereby the inheritance pattern resembles Mendelian inheritance.

It is important to highlight that color blindness is a recessive trait on the X chromosome.

In this case, the mother is a carrier, thereby the probability of passing this trait as a carrier to her son is 50%, whereas the father is normal, thereby the probability of passing this trait to his son is 0%.

Answer:

i have trusted my best to answer

Explanation:

Edit

The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.
