boys have xy sex chromosomes, and girls have xx chromosomes. true false no answer text provided. no answer text provided. question 5 men have a different number of autosomes than women. true false no answer text provided. no answer text provided. question 6 which chromosome specifically are we concerned about when doing sex - linked trait problems (in this class)? 12 21 x y

Explanation:

Question 1 (Boys have XY sex chromosomes, and girls have XX chromosomes)

In human genetics, biological sex determination is based on sex chromosomes. Males (boys) typically have one X and one Y chromosome (XY), while females (girls) have two X chromosomes (XX). This is a fundamental concept in biology related to chromosomal sex determination.

Autosomes are the non - sex chromosomes. Both men and women have 22 pairs of autosomes. So the statement that men have a different number of autosomes than women is false.

Sex - linked traits are traits whose genes are located on the sex chromosomes. In the context of typical sex - linked trait problems (especially X - linked traits which are more commonly studied), the X chromosome (and also Y in some cases, but X is more prominent) is the chromosome of concern. Among the options, X is the relevant chromosome for most sex - linked trait problems (Y - linked traits are less common in basic studies, and 12 and 21 are autosomes).

Answer:

True

Question 2 (Men have a different number of autosomes than women)
