1. ear lobes in people may be free hanging or completely attached to the side of the face. this is determined by a single gene locus; the free hanging allele, e, is dominant and the attached allele (e) is recessive. a. a person has the heterozygous genotype ee. with respect to this gene locus, how many kinds of gametes, eggs or sperm, will this person produce? what will the percent or frequency of each kind of gamete be out of the total possible?

Explanation:

If there is a single gene locus for the ear lobe position a person has the heterozygous genotype Ee can produce two types of gametes: E and e. This is because gametes are haploid (contain only one set of chromosome) so they have only one allele of the gene, in this case dominant E or recessive e.Gametes are formed during meiosis and each gamete will receive one allele.  So, in the case of heterozygous genotype  Ee, person will make gametes that have either E or e with the 50-50% chance. Individual with EE genotype (dominant homozygous) will make only E gamets, while individual with ee genotype (recessive homozygous) will make only e gametes.

If it doesn't have a nucleus its a prokaryote
