the alleles are as follows;
L - lemons with bumpy fruit (dominant)
l - lemons with smooth fruit (recessive)
S - smooth leaf (dominant)
s - spiky leaf (recessive)
parents
one tree - lemons with smooth leaves and smooth fruits
<span>one tree - lemons with spiky leaves and bumpy fruits </span>
if parents show recessive phenotype , this means that the genotype should be recessive homozygous - ll / ss
if parents show dominant phenotype genotype is dominant homozygous or heterozygous
<span>parents - S_ ll x ssL_</span>
<span>f1generation-</span>
<span> bumpy fruits with smooth leaves - SsLl </span>
<span>bumpy fruits with spiky leaves - </span>ssLl
<span>since offspring are bumpy fruits it should either be Ll /LL, but one parent is ll therefore for the offspring to be Ll/ll the other parent should have homozygous LL. Then the offspring will be heterozygous for fruits</span>
<span>offspring have both spiky leaves - ss and smooth leaves Ss. for offspring to have heterozygous and homozygous both, since one parent is already homozygous, the other parent should have heterozygous alleles- Ss</span>
<span>the parents genotypes are Ssll and ssLL </span>
