- Identify the chromosomes in the spread based on their size and banding pattern. Arrange them as shown in the organized picture. I have this image that I have no idea how to start! I get what I'm looking at but I'm having trouble determine if my order is right! Please help me. I've attached the spread of the chromosomes and an example of how they should look.arrow_forwardIn an electrophoretic gel across which is applied a powerful electrical alternating pulsed field, the DNA of the haploid fungus Neurospora crassa (n = 7) moves slowly but eventually forms seven bands, which represent DNA fractions that are of different sizes and hence have moved at different speeds. These bands are presumed to be the seven chromosomes. How would you show which band corresponds to which chromosome?arrow_forwardFigure 17.8 Do you think Dolly was a Finn-Dorset or a Scottish Blackface sheep?arrow_forward
- Now that you have counted the non-recombinant and recombinant asci we want to determine the recombination frequency between the tan gene and the centromere. To calculate the recombination frequency we need an accurate count of the number of non-recombinant recombinant individuals. In the asci the individuals are the ascospores. and 1118 WWW 4 non- recombinant ascospores 4 non- recombinant ascospores 1838 W M M M 500 2 non- recombinant ascospores 2 recombinant ascospores 2 recombinant ascospores 2 non- recombinant ascospores Figure 1.6. The number of ascospores in non-recombinant and recombinant asci. In the non-recombinant asci all 8 ascospores are non-recombinant (see Figure 1.6 above). In the non-recombinant asci 4 of the ascospores are recombinant and 4 of the ascospores are non-recombinant (see Figure 1.6 above).

Get 4 solid wires, 2 long ( 1 green and 1 red ), 2 short ( 1 green and 1 red ). This will represent 4 chromatins of a The wires of the same size are homologous. Red wire will come from the female and green wire from the male. Long green : 1a Long red : 1b Short green : 2c Short red : 2d 2. Let the cell pass the S phase. Replicate or duplicate each chromatin Do this getting another set of wires identical to the original set. Label as before. 3. Join the replicated chromatin fiber using a tape. The tape will also mark the position of the centromere. For the short chromatin, place the tape exactly at the center, while for the long chromatin, place it at ¾ from the end of the wire. This will now represent the chromosomes.arrow_forwardBelow are two pictures of perithecium on microscope slides that have been squished under cover slips so that the asci inside have spread out. In the asci, we can clearly see the tan ascospores (light colored) and wildtype ascospores (dark colored). We will perform our tetrad analysis by counting how many of the asci are non-recombinant and how many of the acsi are recombinant. We can tell which are recombinant and non-recombinant by observing the patterns of the ascospores in the asci. See the patterns of ascospores for non- recombinant and recombinant asci in the table below. Ascospore pattern of non-recombinant asci OOOO OOOOO You will count the total number of non-recombinant and recombinant asci in the two pictures below. You will only count the asci that have a star next to them because these asci can be clearly identified as non-recombinant or recombinant. Select the correct number below after you are done.
