    Question #1: Thomas Hunt Morgan used genetic mapping to map out genes on the chromosomes. He found that alleles that are not genetically linked, can still be on the same chromosome. Alleles A and Z are not genetically linked (recombination frequency is 50%) If the recombination frequency between different alleles are: AZ: 50% G-Z: 50% A-G: 8% T-D: 24% G-T: 39% TZ: 50% A-T: 47% DZ: 25% A. Are A and Z on the same chromosome? Why or why not?...

    Which of the following statement(s) are true? Morgan traced the eye colour gene in flies to the X chromosome. 50% recombinant progeny are observed for two unlinked genes, which is due to the independent assortment of homologous chromosomes in metaphase 1 In very long chromosomes > 50% recombination can be observed. Crossing over between homologous, parental chromosomes is the mechanism of breaking up linkage of two genes to form recombinant chromosomes. The frequency of recombination is directly proportional to the...

    Name Sex-linked traits are genetic char segments of DNA found on chromosomes that Sex-Linked Traits Senetic characteristics determined by genes located on sex chromosomes. Genies are and on chromosomes that carry information for protein production and that are sponsible for the inheritance of specific traits Genes exist in alternative forms called alleics. or a trail is inherited from each parent Like traits originating from genes on autosomes (non-se chromosomes), sex-linked to omosomes), sex-linked traits are passed from parents to offspring...

    1. Crossing over is important because it _____. a. allows the exchange of genes between homologous chromosomes b. prevents variation in gametes c. holds tetrads together d. ensures that homologous chromosomes pair up 2. The M phase of mitosis and M phase of meiosis both occur after interphase. However, the two processes differ in the arrangement and behavior of their chromosomes. How? a. Homologous chromosomes pair up in mitosis, but not in meiosis. b. The pairing up of homologous chromosomes...

    Simulate meiosis by drawing Two pairs of chromosomes with crossing over Assume that two of the genes are on chromosome 1, and one of the genes is on chromosome 2. Allow crossing over to occur between the two genes on the same chromosome. Also, are there multiple ways that the chromosomes could segregate to produce different results? Show them. Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 pairs of...

    7.) Haemophilia is an X-linked recessive disorder. If a male haemophiliac mates with a normal (non-haemophiliac) homozygous woman, would the progeny be affected? a. All males would be carriers. All females would be normal. b. All males would be normal. Half of the females would be carriers and half of the females would have haemophilia. c. All males would be normal. All females would be carriers. d. Half of each sex would be normal and half of each sex would...

What are all the gamete types (gamete genotypes) that their offspring (AaBbDd) can produce? Draw chromosome diagrams if it helps you to answer the question. a. If the three genes are unlinked? b. If all three links are tightly linked (no crossing over)? c. If the first two genes are tightly linked (no crossing over), but the third...
