This is a tutorial video that explains what a Punnett square is and how it can be used to analyze and predict genetic inheritance. The video defines important terms such as genotype and phenotype and explains how alleles operate on a...

In this video Paul Andersen explains how you can combine the power of a Punnett square for an entire gene pool. Hardy-Weinberg equilibrium will remains constant under several constrains and the probability square makes the information...

A brief discussion on Mendel's law of segregation followed by an in-depth Punnet square (monohybrid cross) example.<br/>

Mendel proposed that you inherit a gene either from your mother, or from your father. But not a mixture of both. In this video we are going to look at monohybrid crosses using Punnett squares. A monohybrid cross is the study of the...

RFK Jr. is claiming that scientists do not test vaccines with placebo-controlled trials, specifically against a saline placebo, and that all he’s asking for is that they are tested this way, as all other medicines are.

Gregor Mendel that came up with the correct hypothesis for how inheritance of traits works. Mendel published his ideas in 1866, but it took until the 1900’s for his ideas to be recognised. Mendel studied the inheritance of different...

In this video you will learn how weird and wonderful animals are formed in the process of speciation and the formation of new species. Different selection pressures select for different characteristics. Over generations, the individuals...

Ready to start doing some geometrical problem solving? In these 3 videos we are going to discover 9 different circle theorems. In this video (part 1 ) we’re going to look at 4 theorems inside the circle. And then in part 2 and 3 there...

In this video, the teacher explains how to find the explicit equation for an exponential relationship by identifying the constant multiplier and initial value. The process involves analyzing patterns in the data and using the general...

When you picture a single cell, you probably imagine something super tiny that you had to look at through a microscope. But, there are some huge exceptions to this rule. And we really do mean huge.
