You are in charge of the national Unicorn breeding program.Unicorns can have either swirled or solid horns with the swirled(Sw) phenotype being dominant over solid (sw). Their fur can begold (F⁺), bronze (f^b), silver(f^s) or white (f^w), with the colour allelesfollowing a dominance series of: F⁺ > f^b> f^s > f^w

^{question 1}

a) Which pair could you mate to potentially get some offspringwith silver fur and swirled horns?

Select one:

a. A bronze and swirled horned unicorn with a white and solidhorned unicorn

b. A true breeding gold and swirled horned unicorn with a truebreeding white and solid horned unicorn

c. A silver and solid horned unicorn with a silver and solidhorned unicorn

b) You mate a silver fur, solid horned unicorn, whose mother hadwhite fur and a swirled horn, with a white fur, solid hornedunicorn whose mother had gold fur and a solid horn.  Whatis the probability that the offspring will have white fur (with anytype of horn)?

Select one:

a. 1/16

b. 1/3

c. 1/4

d. 1/2

question 2

Merfolk have three pairs of autosomes and one sex chromosome;males are X0 and females are XX.

In merfolk the genes controlling tail fin shape and scale colourare on different autosomes. Solid tail fin (Ff) isdominant to forked tail fin (ff), and the Fallele is recessive lethal. There are two alleles of the scalecolour gene – C^B(blue) and C^R (red)–C^B and C^R show incomplete dominance withheterozygotes being purple.

The silent trait is X-linked and dominant (X^S) tonormal voice (X⁺).

Atolla is a male merfolk, he has a forked tail fin, blue scales,and is voiceless (silent). Brachy is a female merfolk with a solidtail fin, purple scales and a normal voice.

a) What is the probability that a female child of a matingbetween Brachy and Atolla will be silent (it doesn't matter whattail shape or scale colour the child has)?

Select one:

a. 1/4

b. 0

c. 1/2

d. 3/4

e. 1

b) What is the probability that a mating between Brachy andAtolla would produce a child with a forked tail and purple scales(doesn’t matter whether they are silent or not)?

Select one:

a. 3/4

b. 1/3

c. 1/4

d. 2/3

e. 1/2

c) You mate a female merfolk with blue scales who isheterozygote for silent and a carrier of forked tail, to a silentmale with blue scales who is also a carrier of forked tail. Whichof the following are TRUE statements (you can choose more thanone)

For this question ignore the phenotypes that are unmentioned.For example \"a blue female\" is a blue female who can be any colour,and either be silent or normal.

Select one or more:

a. This mating can produce silent or normal voiced offspring

b. This mating can produce silent or normal voiced femaleoffspring

c. The probability of a female offspring having a forked tailand blue scales is 1/3

d. The probability of an offspring from this mating having aforked tail and normal voice is 1/6
