1. You are analyzing a large family tree with many generations. This family has several members that have an X-linked recessive trait. Would you expect to see this trait equally among the males and females in this family? Explain.
2. Many mammals use X and Y sex chromosomes to determine chromosomal sex. Compare the structures of the X and Y chromosomes. Are they homologous? Why or why not? (You may have to use the textbook to answer this question.)

1.a) How do we know that in humans the X chromosomes play no role in sex determination, while the Y chromosome causes maleness and its absence causes femaleness? c) How do we know that X chromosomal inactivation of either the paternal or maternal homolog is a random event during early development in mammalian females? d) How do we know that Drosophila utilizes a different sex-determination mechanism than mammals, even though it has the same sex-chromosome compositions in males and females?...

Look carefully at the pedigrees below and:
1) indicate whether the transmission appears autosomal or
sex-linked
2) indicate whether the transmission appears dominant or
recessive
3) provide at least two characteristics for each that support
your conclusion.
In general, the following characteristics suggest (but do not prove) specific inheritance patterns: Autosomal recessive inheritance: -affected individuals can be born to unaffected parents -if both parents are affected, all children are affected -observable effect of relatedness (consanguinity) -horizontal" inheritance: trait appears at...
