In the life of Biology by Ur Mum :)

  Have you ever wondered how you get all your different traits, why it happens, and where they started? Well, I'm here to tell ya! We first learned about how crossing genetics work when Johann Gregor Mendel first studied the problems in inheritance. He learned that there are certain traits that are passed from parent to offspring. He performed many different experiments with pea plants.  He determined that there are many different ways that traits can be passed. Referring to my previous blog post there are many diseases that are passed by chromosomes, however, there are inherited diseases, “ The expression of the mutated allele with respect to the normal allele can be characterized as dominant, co-dominant, or recessive. There are five basic modes of inheritance for single-gene diseases: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, and mitochondrial,”( Genetic Alliance, 2008) Even though there are five different types I’ll only mention one ...

THERES DISORDER HERE!          There are so many sets of chromosomes... What happens when you lose some or gain some? There are many ways to explain it, but we're gonna do it my way.      What is a karyotype? This term is referring to the number and appearance of chromosomes. Of the appearance it can include the length, the centromere position, which is the point in which the chromosomes are bound together, and lastly the banding pattern. To obtain a view of an individual’s karyotype, cytologists photograph the chromosomes and then cut and paste each chromosome into a chart (concept to biology, 2017)  There are many disorders that can come from changes in the chromosomes.  To name a few : Albinism, Angelman syndrome, Ankylosing spondylitis, Apert syndrome, Charcot-Marie-Tooth disease, Congenital adrenal hyperplasia, Cystic fibrosis (CF), Down syndrome.  Disorders can be hereditary or a mutation. Inherited di...
