- What does the term recombination mean? What are two causes of recombination?arrow_forwardWhat does a recombination frequency of 50 indicate?arrow_forwardResearchers have discovered that some regions of chromosomes are more likely than others to cross over, these areas of frequent crossing over are called "recombination hot spots". Gene A and B are 500,000 bp apart - the genes are either side of a recombination hot spot. Gene C and D are also 500,000 bp apart but the region containing genes C and D are not near a recombination hot spot. Would the map distance between A and B be the same as the map distance between C and D? Explain your answer.arrow_forward
- Describe two forms of genetic recombination. What functions do they fulfill?arrow_forwardNow 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).

- Below 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.

Your work reveals that the recombination frequency is larger the further the loci are from each other. Why is this?arrow_forward
