A tarantula has eight legs, an arachnid in the order Araneae. A grass spider has eight legs, an arachnid in the order Araneaa. A mouse spider has eight legs, an arachnid in the order Araneae. There is a pattern. All organisms in this order have eight legs. This is what kind of reasoning?

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.
