How do the three types of colorblindness differ in genotype and phenotype?

1 answer:

3 0

Normal colour vision (trichromacy) refers to vision that uses all three types of light cones. People with defected trichromatic vision will be colour blind to some extent and these conditions are called anomalous trichromacy. Three types anomalous trichromacy ( one type of cone perceives light slightly) :

1. Protanomaly – phenotype: reduced sensitivity to red light

2. Deuteranomaly - phenotype: reduced sensitivity to green light

3. Tritanomaly – phenotype: reduced sensitivity to blue

People can also have color blindess as the result of mutation, when loss of function of one cone occurs. This condition is called dichromacy. If there is complete color blindness or monochromacy, the person can’t distinguish any color from grey.

Color blindness is an inherited genetic disorder resulted from mutations on the X chromosome.

The cell you are examining under the microscope appears to contain a nucleus. This organism belongs to the domain:________

igor_vitrenko [27]

The cell you are examining under the microscope appears to contain a nucleus. This organism belongs to the domain <u>Eukarya</u>.

The only domain that includes multicellular, visible organisms including humans, animals, plants, and trees is eukaryote.
Numerous microorganisms, including fungi, algae, and micro-animals, also call it home. Since fungi are so diverse, two distinct fungi may have genetic differences comparable to those between a person and a fish.
Eukarya are eukaryotes, which have organelles and nuclei that are bound to membranes. Prokaryotes are older, less numerous, and simpler than eukaryotes.
Eukarya refers to creatures with nuclei in their cells. Additionally, it is the only realm in which multicellular observable organisms, such as people, animals, plants, and trees, exist. Achaea and bacteria are unicellular organisms without nuclei.

Why is it important that tissues are composed of specialized cells?

KatRina [158]

Cell specialization allows new cells to develop into a range of different tissues, all of which work together to make living organisms function as a whole. The process of cell specialization exactly how cells develop into their diverse forms is complex.

During meiosis I, ____________ chromosomes line up side by side and may shuffle genetic material between themselves.

lozanna [386]

During meiosis I, homologous chromosomes line up side by side and may shuffle genetic material between themselves.

<h3>What is Meiosis?</h3>

In sexually reproducing organisms, meiosis is a unique type of cell division of germ cells that results in the production of gametes, such as sperm or egg cells.
Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome.
Prophase I, Metaphase I, Anaphase I, and Telophase I are the four phases that make up Meiosis I.
It deactivates the sporophytic information while activating the genetic information for the production of sex cells.
By halving the same, it keeps the chromosomal count constant.

<h3>What is chromosome?</h3>

A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code.
Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule.
