SCORPION-xisa [38]

Answer:

100% merle with long coats.

Explanation:

<em>All the offspring produced from the cross would be merle with long coats.</em>

<u>From the illustration:</u>

Merle gene is represented by the genotype cmcs.

fgf5 gene determines the coat phenotype. Let the gene be represented by the allele A. A determines long coat traits and it is dominant over its alternate form, b, which determines short coat trait.

Now, two merle (cmcs) dogs were mated. One is true-breeding for long coat (AA) while the other is true breeding for short coat (aa).

cmcsAA   x   cmcsaa

Progeny genotype = cmcsAa

cmcsAa = merle with long coat.

<em>Since </em><em>A</em><em> is dominant over </em><em>a,</em><em> all the progeny from the cross will be merle with long coat.</em>
