Allele combination. genotype represented by uppercase letters dominance represented by lowercase letters recessiveness RR homozygous Rr heterozygous shows the possible outcomes of genetic crosses punnett square Fruit flies are born with either long wings or short wings. The allele for long wings (L) is dominant over short wings (l). Long winged offspring could have which genotypes?Long wings(L) Short wings(l) LL only LL or Ll Ll only LL or ll Corn stalks grow either wide leaves (W) or narrow leaves (w).What is the genotype and the phenotype of a corn plant that is heterozygous for leaf width? WW wide leaves WW narrow leaves ww wide leaves ww narrow leaves Ww wide leaves Ww narrow leaves A human body cell has 46 chromosomes.
