How Do Plants Reproduce?
Plant reproduction comes in two types: sexual and asexual. Sexual reproduction is similar to human reproduction, in which male pollen and female ovarian germ cells fuse into a new organism that inherits the genes of both parents. Asexual...

Genetics: Linkage Problem #2: Map Distance, Coefficient of Coincidence, and Interference
In this video, we explore another linkage problem in genetics in which we determine the central gene, calculate map distances, and calculate coefficient of coincidence and interference. To see our first linkage problem, click the link...

Mechanisms of Natural Selection Types of Sexual Selection
We touched upon sexual selection when we learned about natural selection. Essentially when there is a variance in the reproductive success of a particular sex for a given species, secondary sex characteristics will develop in that...

Beyond Mendelian Genetics Complex Patterns of Inheritance
We've already learned about Mendelian genetics, which taught us about dominant and recessive alleles and the laws that govern their inheritance. But things are not always so simple. There are situations that go beyond this basic...
