Why can scientists use developmental and functional studies

Why can scientists use developmental and functional studies on model organisms such as mice or Arabidopsis to understand humans or other economically important organisms such as wheat?

Solution

experimental models:

definition: an experimental model is a non-human organism or species that is extensively employed for the purpose of scientific experiments with an aim to understand the biological phenomenon and to make a discovery, which might benifit the mankind.

Crieteria for selection of an experimental model:

for example for the study of mammals the most suitable experimental model is mouse because its genetic, biological and behaviour characteristics closely resemles to humans. ts genome can be easily manipulated aswell. they are suitable for studying physiological and pathological conditions of humans. they are commonly utilizes for genetic studies. example SWR and SWXJ mouse models are genetically modified mose that are used to study ovarian tumours. similarly, Apoe knockout mice, swe mice, tub,DBA/2J, p53 knockout mouse and cftr knockout mice are mployed for studying heart diseses, epilepsy, diabetes,glaucoma, cancer and cystic fibrosis, respectively.

Arabidopsis thaliana is a small flowering plant and is ideal organism for studying plant development at molecular, cellular, organismal and ecological level.it is important because:
