In humans, the allele for dimples is recessive to the allele for no
dimples. If both of the parent's have
dimples, then the offspring-
R. will not have dimples.
S. may have either dimples or no
dimples.
T. must have dimples.
V. cannot be determine based on the
information provided.

it is a learned trait

explanation:

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
