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?...

Birds, unlike mammals, have a sex determination system in which females have Z and a W chromosome (ZW), while males have two copies of Z (ZZ). Another fun fact: most bird species, including chickens, do not have penises. This makes it hard to determine the sex of baby chicks! There’s a gene required for pigmentation located on Z. The “barred” allele (b) of this gene is recessive to the black allele (B). If you would like to easily determine the...

The XY sex determination system is found in Drosophila, where both female X-chromosomes are active. Flies compensate for the two active X chromosomes by increasing transcription of the single male X ~two fold (hence, X/A = 1 in both males and females). What observation makes this mechanism not applicable to mammals?

Human Development-Sex Variations Individuals may acquire chromosomal sex variations, where the number and type of sex chromosomes are not average. A list of some of these variations is below. For each one, predict if the zygote would be assigned male or female or intersex at birth. Later, compare your predictions to the actual phenotypes.
