Question

choose the words that complete the sentences correctly. a choose shows family relationships and the presence or absence of a trait in each member. it can be useful for identifying a trait caused by a(n) choose gene, such as colorblindness, because they are more common in one gender than the other.

Explanation:

The first blank should be "Pedigree" as a pedigree shows family relationships and trait presence/absence. The second blank relates to a sex - linked gene (since colorblindness is sex - linked), so the first dropdown (let's assume the first choose is for the first blank) should have "Pedigree" and the second dropdown (for the second blank) should have "sex - linked" (or relevant term for genes like colorblindness which are sex - linked). But based on the context of the sentence about showing family relationships and trait presence, the first word is "Pedigree" and for the trait - causing gene type, it's a "sex - linked" gene (as colorblindness is X - linked, a type of sex - linked inheritance).

Answer:

First Choose: Pedigree (assuming the first dropdown is for the first blank). Second Choose: sex - linked (assuming the second dropdown is for the second blank, as colorblindness is a sex - linked trait caused by a sex - linked gene).
