Open the article and read it at the level above. Then answer the questions below in your own words.

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the animal development?Controls segment identity along the anteroposterior axis, influencing limb and appendage formation
2. What is the plant development?Regulates floral organ identity (sepals, petals, stamens, carpels) and other morphological features
3. How do homeotic genes cause bugs to grow extra wings?In fruit flies, a gene called Ultrabithorax can be mutated, making the part of the body that normally has legs grow wings instead. This shows how one gene change can change a whole body part.
4. Can plants have homeosis too?Yes! In flowers, genes called MADS-box act like the Hox genes in animals. When they mutate, petals can turn into sepal-like parts or stamens can become petals.

Evolutionary Developmental Biology (Evo-Devo): Field studying the evolution of developmental processes and their role in shaping biodiversity.
Transcription Factors: Proteins that bind to DNA and regulate gene expression, controlling development.
Phenotype: The observable physical or biochemical characteristics of an organism, resulting from its genotype and environment.
Angiosperms: Flowering plants, characterized by seeds enclosed within a fruit.
