Understanding Plant Genetics

Course description

The concepts of plant genetics and inheritance is a very interesting field of science. This free online course will help you fully understand how the gene functions as the chemical basis of genetic inheritance and that all genes occur in multiple forms known as alleles. This plant genetics course will help you clarify how fossilization took place and the different factors that affected this process, along with many other fundamentals.

Are you looking to master the fundamentals of plant genetics? This course will teach you how plants have evolved and their different classifications and especially inheritance in plant genetics. It deals with the selective advantage of reproduction which can either be sexual or asexual. In asexual reproduction, the offspring has the same DNA and alleles, whilst in sexual reproduction, separate organisms combine their alleles, thereby increasing the chances of preserving copies of their alleles. Discover the different causes of changes in DNA and identify the other manufactured mutagenic chemicals that seem to be multiplying in our world. Statically, these mutations are harmful, and the larger-sized mutations significantly increase the probability of affecting a crucial part of the DNA and you will discover the need for DNA repair processes that help counter the adverse effects of mutations.

Firstly, the course will introduce the different concepts of evolution and how evolution by natural selection has changed the abundance of alleles present in various species. How quickly does the process of evolution occur? This course will highlight how slow evolution occurs when compared to the duration of human life. The course content also covers natural selection, an essential factor in evolution. It describes how those species which conform to a particular environment are more likely to survive when compared to those that are less adapted. In addition, you will also work through the two conditions that must be met for natural selection to occur. The first one has to do with the offspring being able to grow to maturity in that particular habitat, and the second one relates to the need for the progeny to have different types of alleles. An overview of the different properties of gymnosperms and all their economic relevance is essential for you to know as someone in botany. Gymnosperm plants grow in all parts of the world, although they tend to thrive in temperate regions. What are the different classifications of gymnosperms? This course will give you an overview of the diverse classes and orders of gymnosperm plants. You will analyze why flowering plants or angiosperms are rated as the most successful and abundant plants in the world today. The final section of the course studies the factors influencing the formation of fossils, evolution of flowering plants, life cycle of angiosperms, ecological classification of plants, and ecosystem structures.

This plant genetics course will interest anyone interested or involved in plant genetics such as those in botany, biology or environmental studies. The basics of plant genetics are an important area of expertise because it forms the basis for what we know about plants, pollination, environmental interactions and much more.
