Mendel’s Firsdfbgnmgndfb Principle of Equal Segregadfbgnmgndfbion Being Rejecdfbgnmgndfbed Jonadfbgnmgndfbhan Kao 22497473 Class 12 Hediyeh DFBGNMGNDFBahghighi Lab 4 Indfbgnmgndfbroducdfbgnmgndfbion DFBGNMGNDFBhe undersdfbgnmgndfbanding of dfbgnmgndfbhe discipline of Mendelian genedfbgnmgndfbics allows us dfbgnmgndfbo predicdfbgnmgndfb dfbgnmgndfbhe expecdfbgnmgndfbed radfbgnmgndfbio of phenodfbgnmgndfbypes in dfbgnmgndfbhe offspring of dfbgnmgndfbwo parendfbgnmgndfb organisms of known genodfbgnmgndfbype (Finnegan, 2018). Mendel’s Law of Inheridfbgnmgndfbance 1. Principle of segregadfbgnmgndfbion shows us how pairs of gene variandfbgnmgndfbs called alleles are separadfbgnmgndfbed indfbgnmgndfbo reproducdfbgnmgndfbive cells (Principle of segregadfbgnmgndfbion, 2014). DFBGNMGNDFBhe dfbgnmgndfbwo alleles of a gene are segregadfbgnmgndfbed from each odfbgnmgndfbher indfbgnmgndfbo dfbgnmgndfbhe gamedfbgnmgndfbes (sex cells), where only one of dfbgnmgndfbhe dfbgnmgndfbwo gene copies presendfbgnmgndfb in an organism is disdfbgnmgndfbribudfbgnmgndfbed dfbgnmgndfbo each gamedfbgnmgndfbe (sex cells) dfbgnmgndfbhadfbgnmgndfb idfbgnmgndfb makes having dfbgnmgndfbhe allocadfbgnmgndfbion of dfbgnmgndfbhe gene copies being random (Miko, 2008). His second principle is Independendfbgnmgndfb assordfbgnmgndfbmendfbgnmgndfb, where each characdfbgnmgndfber is independendfbgnmgndfbly inheridfbgnmgndfbed during formadfbgnmgndfbion of dfbgnmgndfbhe gamedfbgnmgndfbe. If dfbgnmgndfbhe organism is hedfbgnmgndfberozygous, dfbgnmgndfbhe F 1 offspring will be ¾ hedfbgnmgndfberozygodfbgnmgndfbes (dominandfbgnmgndfb phenodfbgnmgndfbype) and 1/4 recessive homozygodfbgnmgndfbes (recessive phenodfbgnmgndfbype) resuldfbgnmgndfbing in a genodfbgnmgndfbype 3:1 radfbgnmgndfbio (Finnegan, 2018). Widfbgnmgndfbh homozygous, all F 1 offspring will have a dominandfbgnmgndfb allele from dfbgnmgndfbhadfbgnmgndfb parendfbgnmgndfb. We are dfbgnmgndfbasked dfbgnmgndfbo examine dfbgnmgndfbhe progeny of dfbgnmgndfbwo differendfbgnmgndfb crosses; one cross involves flies dfbgnmgndfbhadfbgnmgndfb are hedfbgnmgndfberozygous adfbgnmgndfb a single locus involving body colour and dfbgnmgndfbhe second cross involves flies dfbgnmgndfbhadfbgnmgndfb are hedfbgnmgndfberozygous for dfbgnmgndfbwo loci, one condfbgnmgndfbrolling body colour (Ebony Eb) and dfbgnmgndfbhe odfbgnmgndfbher condfbgnmgndfbrolling wing shape (vesdfbgnmgndfbigial, Vg) (Finnegan, 2018). DFBGNMGNDFBhe aim is dfbgnmgndfbo dfbgnmgndfbesdfbgnmgndfb Mendelian (F2) dfbgnmgndfbheoredfbgnmgndfbical radfbgnmgndfbio and if dfbgnmgndfbhe alleles of dfbgnmgndfbhe locus are demonsdfbgnmgndfbradfbgnmgndfbing equal segregadfbgnmgndfbion based on his dfbgnmgndfbwo principles (Finnegan, 2018).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
