Inheriting them Traits

 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 or two…Eventually.

The autosomal dominant and recessive inherited traits are seen in many different ways. The autosomal dominant affects at least two people the offspring and at least one affected parent, also occurring in every generation. The autosomal recessive both parents of an affected person are carriers, not typically seen in every generation (Genetic Alliance, 2008)



Joke of the blog: 

What did the football player/genetics student use to find the genotypes

possible from a particular cross after failing three times using the branching method?

A "punt-it" Square.

 

There are many types of traits outside of diseased that pass on characteristics, dominant and recessive traits. “A trait is defined as a variation in the physical appearance of a heritable characteristic. The characteristics included plant height, seed texture, seed color, flower color, pea-pod size, pea-pod color, and flower position.” (concept to biology, 2017). Dominant traits are ones that take over in a crossing of genetics. Recessive are traits that disappear in crossovers, to eventually re-appear later in the crossing of plants or mammals. There are also other types of dominance, incomplete and co-dominance. Incomplete dominance is where two traits are mixed to create a mix of the two instead of one taking over the other, an example being a red and a white flower mixing and creating a pink flower. Codominance is where both traits are dominant but are different so when they are mixed both traits are visible. 


Fun fact: If someone ever comes up to you and says “Hey, you look just like your mother/father”  the reason is because of heredity, which means that traits from your parents are passed down to you creating that similarity between the two. 

All of these come together and create each one of us in a different way. Traits whether they are recessive or dominant makeup what you and your siblings are. Your parents are the trait carriers and both carry dominant traits whether you know it or not. Why is it important? Its important because it helps us understand where we get all of our physical traits from and also teaches us that some traits can only be given to some offspring. Which gives us the knowledge to understand some forms of our basic biology.

  Ecosystems and The Biosphere  What is an Ecosystem and Biosphere? Ecosystems are a community of many living organisms and their nonliving environment. Ecosystems can range in size from a tiny pool of water to the largest rainforest. There are a collection of three different types of ecosystems. The first is freshwater, freshwater ecosystems are lakes, reservoirs, rivers, wetlands, and streams. “Freshwater ecosystems are interactive systems within which biotic species and their growth and adaptation, and associated biological productivity, nutrient cycling, and energy flows among inland aquatic microbial, plant, and animal communities, are integrated with their environment,” (Wetzel 2001) this ecosystem uses the vapors from saltwater ecosystems, which the salt is separated when the water turns to steam, and eventually is released as rain or snow into our freshwater systems. Of course, the following system is marine ecosystems. “ Marine ecosystems are aquatic environments with high le

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 disorders may come up when chromosomes go through meiosis abnormally.  The ty
