In some plants, pointed leaves (p) are dominant over rounded leaves (p). a plant with a genotype of pp

According to Mendel’s laws of dominance, when a plant with dominant trait is crossed with plant with recessive trait, it results into dominant phenotype in F1 offspring. In the given question, a plant with pointed leaves (P) are dominant and plant with round leaves (p) is recessive. On crossing a pointed leaves (PP) with a plant with round leaves (pp) a heterozygous (Pp) pant with pointed leaves will be produced.

the correct answer is phenotype

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
