Life cycle 1

In the lectures of this course, we describe each stage of the life cycle, starting with embryonic development (including organ development, cell differentiation and growth processes), through the acquisition of reproductive capacity (including the stages associated with meiosis and gametogenesis), and ending with fertilization. This life cycle is discussed in detail in metazoans and angiosperms, and allows you to consolidate your knowledge of the transmission of genetic information. This will allow us to solve Mendelian genetics problems including sex and epistasis effects during the tutorials of this course.

By following this course, you will be able to describe the different stages of the life cycle of an organism (vertebrate or angiosperm), to define the stages of alternation between haploid and diploid phases, to characterize the stages of cell differentiation, and to solve problems of Mendelian genetics including effects related to sex or epistasis.

Among the UEs of L1S1, you must have validated :

HAV101V From molecule to cell: a good knowledge of the cell's constituents and their function is expected

HAV107B From cells to organisms: knowledge of the functions performed by all multi-cellular biological organisms, and knowledge of the diversity of these organisms is expected

HAV108B From organisms to ecosystems: a minimum knowledge of the relationship between an organism and its environment is expected

Recommended prerequisites*:

In addition to the knowledge acquired in L1S1, it is recommended to have solved Mendelian genetics problems at the high school level, to know the processes of mitosis and meiosis, and the differences between these two processes.

The acquisition of competences in this UE will be evaluated in final control.
