people? A person’s culture informs the way he or she views others and the world because of one’s personal past and experiences affecting their point-of-view and/or perspective. Knowing that culture defines who we are‚ we can affect others as they affect even more people‚ etc. Acting like a chain reaction in how we view the world. How we view the world can be told from many different sources such as; “Two Ways to Belong in America”‚ “An Indian Father’s Plea”‚ and “Two Kinds”. These sources explaining our

Genetics Experimental Analysis Set #2 Linkage 1. In gorgonzolas‚ there are three recessive traits that affect the organism’s appeal: shrunken fruit‚ foul-smelling flowers‚ and short height. A heterozygote was crossed with a homozygote‚ yielding the following offspring: 46 - foul-smelling 44 - shrunken fruit‚ short height 8 - short height 8 - shrunken fruit 7 - foul-smelling‚ short height 6 - foul-smelling‚ shrunken fruit 3 - foul-smelling‚ shrunken fruit‚ short

recessive → masked by dominant allele on other chromosome (females are carriers for the trait) Linked genes -two or more genes found on the same chromosome -if the genes are linked‚ they would always be transmitted together but this violates the principle of independent assortment If recombination(crossing over) occurs‚ principle of independent assortment is not violated Recombination – combination of alleles on the offspring chromosome in the gametes are different from the combination of alleles

Meiosis is the process in sexually reproducing organisms where cells divide. The cells produced during meiosis have half the chromosome number as the original cell. There are two cell divisions in meiosis‚ meiosis l and meiosis ll. These cell divisions produce 4 hapolid daughter cells. Haploid cells contain only one set of chromosomes‚ which is written as n. Meiosis consists of nine phases. In meiosis the interphase l the chromosomes replicate and the centrosome duplicates in one diploid cell

Dichaete/Stubble male fruit flies represented our Discriminant Cross one (DC1). The DC1 piloted that the unknown mutation is sex linked dominant. Knowing the mutation is sex linked gives evidence that it is located on chromosome 1. Discriminant Cross two (DC2) is then performed basically to execute a check for DC1 by crossing a wild type female with a Plum/Stubble male fruit fly. In our case if the cross was done correctly all the females should carry the uknown mutation and none of the male progeny
