<span>I'm not sure, but I know that their colour changes as the fish matures.

"Young fish are bright yellow with blue spots near their eyes. As they get older, they become blue over most of their body with a yellowtail. Full-grown adults are a rich blue from head to tail, with narrow dark lines running the length of the body."

Red-green color blindness is an X-linked recessive disorder. A woman with normal vision whose father was colorblind has children
andrey2020 [161]

Answer:

The probability of their first child being colourblind is 1/4

Explanation:

Red-green color blindness is an X-linked recessive disorder.

A woman with normal vision whose father was colorblind has children with a man with normal color vision.

In an X-linked condition, the males only need to get one copy of the affected allele to have the condition and this copy is also inherited by a female offspring.

So in this case, the woman receives the affected recessive allele copy from her dad but since she still has normal vision, she received the normal copy from her mom so she is heterozygote for the trait.

The woman with normal color (XRXr) has a father who is color blind (XrY) has children with a normal man (XRY)

The cross would be

XRXr x XRY

XR Xr

XR XRXR XRXr

Y XRY XrY

Probably of having an affected child is 1/4. Thus, the probability of their first child being colourblind is 1/4

The science of describing, naming, and classifying extant and extinct organisms is:__________
Sloan [31]

The answer is Taxonomy.

The science of describing, naming, and classifying extant and extinct organisms is <u>Taxonomy</u>.

What is taxonomy?

All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species. Taxonomists identify, describe, and classify species, particularly those that are novel to science, using morphological, behavioral, genetic, and biochemical observations. Taxonomy recognizes and catalogs the elements of biological diversity, offering the fundamental information necessary for the management and application of the Convention on Biological Diversity. Unfortunately, our understanding of taxonomy is far from complete. Taxonomists have identified roughly 1.78 million species of animals, plants, and microorganisms throughout the past 250 years of study, but the true number of species is unknown and likely between 5 and 30 million.

Generally speaking, superficial categorization of living things develop according to necessity. Any crawling object, such as a snake, earthworm, intestinal parasite, or dragon, has been referred to, respectively, by the Anglo-Saxon phrases worm and fish. There are more anatomical distinctions between a shellfish and a starfish than there are between a bony fish and a man, despite the fact that the terms shellfish, crayfish, and starfish all include the term "fish." There are many different types of vernacular names. The English robin (Erithacus rubecula) is not the American robin (Turdus migratorius), for instance, while the mountain ash (Sorbus) only superficially resembles a real ash.
