Item 10 10 of 15 > A cross in Drosophila melanogaster involved the recessive X-linked genes for white eye (w), yellow body (y), and cut wings (c). A wild-type tri-hybrid female was crossed with wild-type males and only the male offspring were tallied.

Three pt croSS (1) Two genes are on separate chromosomes (i.e., unlinked). One homologous pair of chromosomes carries the 'A' and 'a' alleles, while another homologous pair of chromosomes carries the 'B' and b' alleles. Based on what you know about Independent Assortment and probability, what percent of the time will the following occur: 1. 'A' goes with 'B' and 'a' goes with 'b'? 2. 'A' goes with 'b' and 'B' goes with 'a'? Therefore, can we compute a distance of 60 map units for two genes by a two point cross? Yes or No. Why? Mendel observed 7 traits. Pea plants have seven chromosomes. It is now known that the traits studies by Mendel were not on separate chromosomes. Do you think that Mendel accurately reported his experimental findings? 129 MacBook Air
EXTRANUCLEAR INHERITANCE 1. In the four o’clock plant Mirabilis jalapa, leaf color is governed by organelle inheritance of either chloroplasts (green) or leucoplasts (white), or both (variegated). What are the F1 phenotypes from the following crosses:
For 21. What are the genotypes of the F2 generation. Of the F₁ generation. Of the parents 22. If it were possible, how would you determine whether a tall individual is heterozygous or homozygous? 23. How do the observed phenotypes of your seedlings compare with the expected F2 ratio? To calculate your expected ratio numbers given the total number of seedlings that you counted use the following steps: A. Determine your expected ratio. For a monohybrid cross between two F1 plants, both heterozygous for the trait, you would expect a 3:1 ratio. If you add 3+1, it equals 4. Therefore, each category is a fraction of 4. This means that you expect the following fractions 3/4 and 1/4 for the two phenotypic class. B. Determine your total number of corn plants actually counted. C. Multiple each fraction by the total number of seedlings you actually counted. a. For example, if you counted 85 seedlings, you would expect the following: i. 3/4 X 85= 64 tall seedlings ii. 1/4 X 85 = 21 dwarf seedlings…
