A man inherits dominant allele for the trait from father and recessive allele from mother. what trait will this man expressed which alleles will his sperm cell contain??

Explanation:

The dominant trait, since he has a dominant and a recessive allele.

Sperm cells are haploid, meaning contains only one of the two alleles available, in a random fashion.  Therefore on the average, half of his gametes (sperm cells) will have the dominant allele, and the other half will have the recessive allele.  

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.

answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;
