reproduced the outcome of 30 beetle population size that has a ratio of 1:1:1 in red, orange and yellow phenotypes and indistinguishable predation ratio (1:1:1) over 20 generations. 3 trials out of 4 showed an analogous trend, the highest frequency of alleles is the yellow phenotype after the 14th generation in trial 2 and 3 and 13th generation in trial 4, making the overall surviving beetle population by 20 generations. The red beetle population showed a drastic extinction after the 13th…

Introduction It is estimated that there are one trillion species on earth despite all being originated from one common ancestor, LUCA. In this essay the importance and origin of diversity within species and between species is explored using Coleoptera as the taxonomic group. Coleoptera is the most dominant order of insects with 350,000-400,000 species, this is 40% of all insect species (Gillott, 1995) and the largest order in the animal kingdom. The degree of differences between individuals is…

relatives, Neandertals, both possess the same mutation that causes a null allele at the blood group gene, giving individuals the O blood type phenotype, and the allele’s frequency in both humans and sampled Neandertals suggests that the allele confers some advantage to its possessor and underwent positive selection in the common ancestor of both species (Lalueza-Fox et al. 2008). Focusing more on the human lineage, other alleles resulting in the O blood type emerged at least three times in the…

travelling between the two water bodies; the small group of migrants would in turn be genetically unrepresentative of the original creek population. The disequilibrium of the Hardy-Weinberg proportions, generalized as (p1 + … + pn)2 =1, pn representing the allele frequency if a particular locus is polymorphic (as in the case of microsatellites), indicates the presence of an evolutionary force influencing the decrease in the frequency of heterozygosity of the pond population. The founder effect…

OVERVIEW: Huntington's disease (HD) is an inherited disorder that causes degeneration of brain cells, called neurons, in motor control regions of the brain, as well as other areas (NINDS, 2016). Huntington’s disease is caused by a mutation in the gene for a protein called huntingtin. The defect causes the cytosine, adenine, and guanine (CAG) building blocks of DNA to repeat many more times than is normal (NINDS, 2016). Huntington’s disease is a progressive brain disorder that causes…

Also the different allele patterns such as incomplete dominance (a mixture of both parental alleles in the offspring), and codominance (both parental alleles are expressed in the offspring). The different laws of inheritance are also part of the week's concept, such as the law of dominance (in a heterozygous one trait usually the dominant…

are HLA alleles which may increase the risk for developing more severe, erosive disease. Having one DR4+ allele increases this risk, while having two copies confers an even higher risk of developing this more severe form of RA. The more severe form includes extraarticluar disease manifestations such as vasculitis, rheumatoid lung disease, and Felty’s syndrome. Furthermore, joint damage is more rapid and progressive in patients with two alleles (Barton, 2015). Third, there are HLA DRB1 alleles…

distinct two parental alleles in traditional genetics . The intragenic recombination causes a distinct fragment pattern from both parents (Okagaki and Weil 1997). To easily discover the intragenic recombination, two individuals carried non-functional alleles of targeted genes, whose intragenic recombination causes a functional allele and obtained a distinct phenotype change, are priority used to develop a population for estimation of intragenic recombination rate. The functional alleles/plants…

future husband will be able too. The trait I did is a dominant trait, As stated by Alfred Sturtevant, “If you inherited one or two copies of the dominant “tongue rolling gene” (T) allele from your parents, then you would be able to roll your tongue. If you inherited two copies of the recessive “tongue rolling gene” (t) allele instead, then you would not be able to roll your tongue.” My dad was dominant over my mom for tongue rolling their for both my brothers and I received the trait. There…

not use the word “most,” because the word “most” contradicts the statement the author is saying. The author may not be taken literally when using this in their writing, because they are contradicting themselves. The author did use a good list of alleles that somehow have an effect on addiction, or affected by addiction. This list showed that the author had used information from a journal, diary, interview, or research, but chose not to cite the source. This also makes the source not as…
