In chickens the dominant allele Cr produces the creeper phenotype (having short legs). However, the creeper allele is lethal in

Svetllana [295]

Answer:

66.6% of the living progeny would be creepers

Explanation:

The creeper allele is Cr for both parents this means that there is a 50% chance that they will pass the C or r trait to their progeny. In this scenario the deleterious inheritance of rr will be 25% so this will not be factored in this answer. The other progeny is CC 25% and Cr 50% for genotype only

The new calculation for living progeny is this: Of the chances of three living progeny there could be one normal CC and two creepers Cr. This means that 33.3% of the living progeny is normal CC and 66.6% of the living progeny are creepers Cr.
