The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. A genotype is the genetic makeup of the organism. This is shown by the three genetic conditions described as(BB, Bb, bb) and phenotype is the trait those genes express. How do you fill out punnett squares?
What is microbiology? What does it entail and what is the reason or importance for the study of micro biology.
I remember when I first learned about Mitosis in biology,I was like “oh ok that makes sense” and then I learned about Meiosis and my immediate reaction was… “didn’t we just learn about this”? It definitely does not help that they both start with “M’s”, I would continuously get them confused and was not really…
Dihybrid crosses. Total nightmares, right? AaBb x AAbb, etc. All too often your teachers will show you a giant 4×4 gamete Punnett to find the answer. They’ll tell you that there are too many alleles for a simple Punnett square. But that isn’t true. As a matter of fact, you can use the little squares…
Blood types are one of the most interesting and applicable examples of genetic inheritance. However, they can be a bit tricky to wrap your head around. This problem challenges you to apply a basic understanding of blood type genetics to a real-life problem (which is something that teachers love to do on tests!)
This problem discusses the main differences between osmosis and diffusion, as they are both passive transport mechanisms but differ in terms of how these processes occur.
Mendel formulated a theory of inheritance based on experiments with garden peas, proposing that parents pass on to their offspring discrete genes that retain their identity through generations. The fundamental principles of inheritance are called the law of segregation and the law of independent assortment.
