    This article was written in response to the 1990 US Census, in which they asked parents of biracial children to check the single race box. The researchers wanted to know, the reason behind each parent’s choice. For their mixed-race sample data, they used the three most common racially mixed household types (Asian-white, black-white and Latino-white). For their geographic area, they used the twelve major cities with the largest multiracial population. To get detailed information about each…

    Inversions and reciprocal translocations do not usually cause a phenotypic effect because of the person who is possessing these are able to equal the look alike numbers genetic components as a ordinary person. They would be able to possess a regular phenotype. It is also possible that the disengagement of the position of the chromosomes was able to influence the gene that was attempting to be expressed. 3. A woman who is…

    Gene deactivation is essentially gene suppression, which is another topic I learned in class. Gene suppression is described as a second gene blocking the mutant phenotype of the second gene. Through suppression, the phenotypic ratio of progeny resulting from a cross between two heterozygotes is altered from a 9:3:3:1 ratio that is generally expected. The example of such a cross provided in class allowed me to understand…

    Father of modern genetics, Gregor Mendel, is well known for his garden pea plant experiment in which he discovered the phenomenon of “dominant” and “recessive” traits (Orel, 1996). His experiments led him to what is known as today’s Mendel’s Laws of Inheritance: Law of Segregation, Law of Independent Assortment, and Law of Dominance (Orel, 1996). The Law of Segregation states two alleles for a heritable character separate from each other during gamete formation and end up in different gametes…

    allele for a precise trait isn’t completely expressed above its paired allele, in which the expressed physical trait is a mixture of the phenotypes in both alleles. Examples of incomplete dominance include plants normally snapdragons, they inherit peculiar pigmentation when they are cross pollenated.…

    trait---while the Curly Wing genetic trait is a Dominant allele trait. In genetics, recessive and dominant genes are key factors in determining the phenotypes and genotypes in the offspring. Dominant genes are the expressed trait shown in the offspring, meaning if two alleles of a pair differ, the dominant gene is the gene that determines the phenotype and genotype. The recessive gene is the masked trait, meaning if two alleles of a pair differ, the recessive gene is the trait that…

    experiments, I learned how to properly cross the monohybrid and dihybrid crosses. I also learned from those experiments how to determine if a trait is autosomal or sex-linked, based off their phenotypic ratios. If the phenotype shows a 3:1 ratio then the trait is autosomal, and if the phenotype shows a 1:1 ratio then the trait is sex-linked. I also learned from the Reebop lab experiments, that independent assortment occurs in all the crosses. From the data given, I first assumed that all the…
