Because the tall trait covered up the short trait the tall trait is considered dominant and the short trait is considered recessive (McClean,…
RESULTS: An experiment was conducted to document the patterns of evolution in the fictional species, Cannus stannous. Fitness of the C. stannous population is determined solely by its ability to retain heat. Three genes determined heat retention; can size, skin type, and water level. Each gene had three alleles, producing 27 possible phenotypic combinations (Table 1).…
(2015) is a template for a drawing that records information regarding familial relationships that span at least three generations. (p. 116) The genogram focuses more on the genetics than the external support system. When looking at the genogram with families, they become more involved in the disease process and supporting the patient.…
Winners will win a prize. Teacher will ask students to reflect on the lab, which traits were dominant in the class drawings and which were recessive. How many of the portraits had the recessive traits? They will discuss genetics and generations in families. The class will discuss how there can be many different traits in one family.…
A woman is a carrier of Duchenne muscular dystrophy (XAXa) and her husband is not Duchenne muscular dystrophy (XAY). What is the probability their child will be duchenne muscular dystrophy? 9 Provide the solution to your problem. Include text and/or a Punnett square table explaining your solution. Include the appropriate probabilities.…
Mendel studied genetics using flowers and pea plants. In a monohybrid, concerning one trait, cross, he crossed a purple (PP) plant with a white (pp) plant, and the offspring were all purple (Pp). He also crossed yellow, smooth peas (YYRR) with green, wrinkled peas (yyrr), which is a dihybrid cross because it involves 2 traits. The offspring of the cross, called F1 offspring because they are the first generation, resulted in 100% round (Rr) and yellow (Yy). The offspring were then intercrossed, and the offspring (F2 generation) resulted in 9:3:3:1 round and yellow (RRYY), round and green (RRyy), wrinkled and yellow (rrYY), and wrinkled and green…
Review Questions # 5 2. Distinguish between autosomal dominant and autosomal recessive disorders and provide a couple examples of each. When dealing with genetic disorders its important to understand how they are inherited. There are two ways a child can inherited a genetic disorder from their parents. Autosomal dominant disorder is where one parent has a genetic disorder in which it has already manifested such as familial hypercholesterolaemia, marfan’s syndrome, and achondroplasia(dwarfism) and this dominant gene is inherited by their child who will also develop the disorder.…
The descendants of M93, a large portion of the population, carried a high frequency of the deleterious recessive alleles which caused them to have short lifespans, supported by the results of the low viabilities of M93 progeny in Table 2. When they died, a significant decline in population size…
In Inheritance: How Our Genes Change Our Lives and Our Lives Change Our Genes, author Sharon Moalem uses a concoction of historical happenings, real-life experiences, and patient case history to portray two main biological concepts: deviations from Mendelian genetics and epigenetics (Moalem, 2014). In regards to the AP Biology curriculum, these two concepts relate, respectively, to the third and fourth big ideas that make-up the course’s framework. The third big idea in the AP Biology curriculum declares that, “Living systems store, retrieve, transmit, and respond to information essential to life processes” (The College Board, 2015). The continual survival and growth in all living organisms hinge on the genetic information they inherit from…
Each group was given the choice to cross either gray or tan Sodaria. Secondly each group would have to distinguish each asci to have undergone Mitosis I (MI) or Mitosis II (MII) crossing. This was able to be distinguished between the pattern of light and dark circles contained within the asci. Thirdly, after compounding the data between the class, students will have to see which genetic cross was more favorable. Finally, students will be comparing their own data with the expected value for the gray and tan…
SIMULATION CROSS BETWEEN A HETEROZYGOUS FEMALE AND A HEMOPHILIA MALE BACKGROUND INFORMATION The survival of the human species throughout the last millions of years has been solely based on the randomized process of genetic inheritance from one generation to the next generation. Instead of duplicating their genetic information and create identical offspring, humans produce sex cells, through the process of meiosis, that carry only half of the genetic information, and fertilize them in order to produce non-identical offspring (Science Learning Hub, 2011). The ability to create unique offspring for every –sexual reproduction- allow a greater chance of survival and mutations.…
Drosophila melanogaster also known as the common fruit fly is mostly associated with fruits and vegetables, however it can originate from other sources. Drosophila melanogaster has a common life cycle of fifty days. In that time period female fruit flies lays several eggs. Similarly, fruit flies develop from larvae like other flies (Glick, Neimeier and Aiello). Drosophila melanogaster can reproduce anywhere that has fermented organic matter that stays moist.…
Research shows that parents with altered gene expressions…
How Genetics Affect Me If you really think about your traits/genes and where they come from it's quite interesting. See you have heritable/genetic traits which of course you get from both your parents, then there is this thing called, hybrid which is two different things that are put into one. Finally you have non-heritable traits which basically means that you don’t get things from your parents. So read more if you want to know more about traits and how cool they are.…
There are various factors that can change how a phenotype is displayed. Although DNA has decided what way different traits should appear they don't always appear the way they should based on other factors. The different factors are dominant and recessive genes, Multiple Genes, New Gene Mutation, Phenotypic Range, and Phenotype Plasticity. There are several factors that are not environmental that can effect the way a phenotype is displayed. An example of Dominant and Recessive genes are eye color.…
