<h2>Anterior-posterior orientation</h2>

Explanation:

Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established  

  • Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
  • They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments
  • Movement in some flatworms is controlled by longitudinal,circular and oblique layers of muscle
  • Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants

Explain Segregation of alleles, using pea plant triats in your example. Help
earnstyle [38]
Segregation of alleles happens when the pair of alleles of each parent separate and only one allele passes from each parent on to an offspring. So if you had heterozygous tall plants and mated them (Tt x Tt), they would each separate into T and t, allowing each offspring to get either a T or a t from each parent. The possible genotypes would be TT, Tt and tt.
