Question

Which of the following properly describes a cross between a Mythosuar (whose genetics are very similar to our lizards and similar to us) who is homozygous dominant for horn shape (downward) for but heterozygous for sternum bone length and an individual who shows the recessive phenotype for both characteristics? (H = downward horns, h = straight hornes, S = broad sternum, s= short sternum fingers)

		WWSs x wwSs
		none of the above
		WWSs x wwss
		Ws x ws
		WwSs x WwSs

Answer 1

Ans) The correct answer is "C"

(There is something wrong in the question or answer choices.It is given in the question that alleles for horns is represented by the letter H or h . But in the options it is given as W or w).

We have to find homozygous dominant for horn shape (downward) which will be HH , heterozygous for sternum bone length which will be Ss . And an individual with recessive for both the characteristics will be hhss. Thus,the cross representing will be HHSs x hhss.
