Korolek [52]

Hello!! Since there is no mention of weight in the question, I would assume that she is pregnant. Whenever someone's blood pressure is low, it is referred to hypotension. Whenever someone's blood pressure is high, it is referred to hypertension. I would say your best answer is A - She has hypotension because she is pregnant. I hope that is the right answer you are looking for. Have a great day!! :)

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
