Can parents with only recessive alleles give their child a dominant trait?

Kids inherit traits from their parents. Sometimes when two parents with different traits have kids, all the kids end up with only one parent's trait even though the children inherited both. In this case, one trait is said to be dominant over the other recessive one... This situation is called incomplete dominance.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
