I need more details to answer your question
In a dominant cross, the chance of the dominant phenotype showing up in one of the offspring is 3/4, since the dominant genes are being shown here.
I do believe it's a recessive trait. I hope that helps
The answer is letter D. The macronucleus is not exchanged during conjugation. <span>It normally contains the working duplicates/copies of genes necessary to support an enormous cell. Macronucleus is formed by a direct division of the polyploid nucleus right after conjugation then followed by series of internal gene replication that is not oftenly occurring in micronucleuse.</span>
