Please answer all of the questions.

Spider-Man and Spider-Woman are planning to have children in thenear future. Spider-Man is able to spin webs (S) and cling to walls(C), whereas Spider-Woman can spin webs butcannot cling to walls. If both of these traits areinherited in a dominant manner (i.e., the dominant trait willalways mask the recessive trait), Spider-Man is heterozygous foreach trait, and Spider-Woman is heterozygous for the web-spinningtrait...

What would be the phenotypicratio of the F₁ generation? Please notethat: \"S\" = ability to spin webs; \"NS\" = cannot spin webs;\"C\" = ability to cling to walls; and \"NC\" = cannot clingto walls.

	a.	2 S/C : 6 S/NC : 6 NS/C : 2 NS/NC
	b.	4 S/C : 4 S/NC : 4 NS/C : 4 NS/NC
	c.	8 S/C : 2 S/NC : 2 NS/C : 4 NS/NC
	d.	6 S/C : 6 S/NC : 2 NS/C : 2 NS/NC
	e.	None of the above

In humans, the ability to roll one's tongue is a dominant trait(R). A woman who can roll her tongue is married to a man who cannotroll his tongue. The couple's daughter, Nia, can roll her tongue,but their son, Michael, cannot.

What is the genotype of the mother?

	a.	RR
	b.	Rr
	c.	rr
	d.	Either A or B
	e.	Either B or C

Characteristics (or traits) of an organism, such as thosedescribed in the examples above, are said to be heritable. In thiscontext, the term \"heritable\" means...

	a.	Able to induce production of hair in various species
	b.	Traits that are most frequently seen within a given populationearly in development
	c.	The ability for traits to be passed down from parent tooffspring
	d.	Traits that are only present when both parents are homozygousdominant
	e.	None of the above
