4.Eyelash length is an inherited trait. In the human population, there is an eyelash length gene. There are two possible variants of this gene—an allele for long eyelashes (> 1cm) and an allele for short eyelashes (1 cm or less). The allele for long eyelashes is dominant (L) and the allele for short eyelashes is recessive (l). An individual who is heterozygous for eyelash length would have which of the following genotypes?     A.Short eyelashes     B.Ll     C.LL     D.Long eyelashes
