When colorblind women married a male with normal vision, all their daughters have normal vision and all their sons are colorblin
worty [1.4K]

Answer:

X-linked recessive

Explanation:

The trait is a sex-linked trait because the daughters are not colorblind, but the sons are. We know this its recessive because the daughters have inherited the mother's X chromosome that has the colourblindness trait, but are not colorblind because the father's X does not have the colourblindness trait. The sons are colourblind because they inherited the X from their mother with the colourblindnese trait and a Y from their father. The colourblindness trait or normal vision trait is not carried on the Y, so the mother's X chromosome's trait is expressed.

Sorry if it's confusing i tried my best to explain it

Trichodesmium is a nitrogen-fixing cyanobacteria. Why might this cyanobacteria be important to other organisms in nitrogen-poor
eimsori [14]
Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>
