This paper will explain the structure of DNA‚ discuss how the structure of DNA allows it to serve as the basis for inheritance‚ examine how meiosis allows DNA to be divided into gametes‚ and describe how this relates to Gregory Mendel’s patterns of inheritance. DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine

allele Nnii which produced the blood type O and nail patella syndrome. 2. Determine all possible parental and recombinant gametes produced by Greg and Susan. Greg’s parental gametes are NI^ and ni; Greg’s recombinant gametes are nI^A and Ni Susan’s parental gametes are nI^B and Ni; Susan’s recombinant gametes are NI^B and ni 3. Determine the frequency of each type of gamete.** From the case study‚ we see that the dominant nail- patella trait resides on chromosome and is 10 recombination map units

of the offspring’s genetic makeup by creating haploid gametes. Most organisms form two different types of gametes. In these anisogamous species‚ the two sexes are referred to as male and female . In isogamous species‚ the gametes are similar or identical in form‚ but may have separable properties and then may be given other different names . For example‚ in the green alga‚ Chlamydomonas reinhardtii‚ there are so-called "plus" and "minus" gametes. A few types of organisms‚ such as ciliates‚ Paramecium

It is important that cells go through mitosis because it makes each new cell contain the same gentic information. If meiosis did not occur the reproduction would cease to exist. Mitosis is the process of chromosomes dividing. There are four steps that it goes through. Between cell division the cells are in interphase. During this there is cell growth and the genetic material such as DNA is contained in the chromosomes‚ duplicated so that when the cell divides each new cell has a full version of

placed into gametes during meiosis in the F generation. The F can be thought of as having been formed 1 1 from two haploid “input” gametes. In this case‚ the F is a dihybrid with AB on one chromosome and ab on the other 1 chromosome. You can tell this by looking at the parents. The F1 hybrid got AB from one parent and ab from the other parent (AB/ab). A dihybrid that is AB/ab can produce four possible “output” gametes through meiosis. Output gametes that match one of the input gametes are nonrecombinant
