- Examine the trait distribution of Specific Leaf Area (The ratio of leaf area to dry mass, SLA), below. The dotted normal distribution represents the natural pattern of SLA observed in nature. The histogram below the dotted curve represents the distribution of phenotypes when the plant is grown in a single common environment. The numbers above the bars represent the observed phenotype ratio. a a) How many polygenes encode for this trait? b) Assuming the minimum observed phenotype in a common garden was 8sqm/kg and the maximum observed phenotype was 20 sqm/kg, what is the contribution of each allele in this polygene?Use keyboard only to enter your answer below. ALL WORKING MUST BE SHOWN Problem 1) mutation in a gene on chromosome 15 that codes for an enzyme. The disease is an inherited autosomal recessive condition which is Tay-Sachs disease is caused by loss of function found amongst Ashkenazi Jews of Central European origin. In this population, 3 in 5,200 children are born with the disease. What proportion of the population are carriers (heterozygotes) for this disease?the photos below show flowers from two Arabidopsisplants. The plant on the left is wild-type (unmutated); theother carries a mutation that causes its flowers to havesepals and petals instead of stamens and carpels. Themutation inactivated one of the plant's ABC floral identity genes. Refer to Figure 10.8 and decide which gene(A, B, or C) has been inactivated
- You and your lab partner performed a complementation test for five recessive histidine auxotrophs. Your plate looks like this: 1 2 3 4 5 1 2 3 4 5 growth no growth What do the gray patches represent ✓ [Select ] What do the tan patches represent? diploid histidine auxotrophs diploid prototrophs haploid histidine auxotrophs haploid prototrophs What is the composition of the medium for this test? [Select] The data contains a conflicting result due to a false positive (that is, it showed growth where it should not have grown) because your partner inoculated a patch too heavily. Which cross most likely led to this result? [Select] How many complementation groups are described by this data, taking into account that a cross yielded a false positive result? [Select]In the DNA, different alleles of a gene have a different sequence of ***18. Complete this flowchart to show how different alleles can result in different characteristics. different sequence of in transcription > different sequence of in a protein translation > different structure and function of the protein (e.g. normal enzyme vs. defective enzyme) > different characteristics (e.g. normal color vs. albino) In this section, you will analyze how different alleles of the hemoglobin gene can result in sickle cell ar vs. normal health. ***19. Compare the nucleotide sequence in the "Beginning of Normal Hemoglobin Gene" vs. the "Beginning of Sickle Cell Hemoglobin Gene". What is the only difference?"In the small intestine, stem cells in the crypts divide asymmetrically to maintain the population of cells that make up the villi; after each division, one daughter remains a stem cell and the other begins to divide rapidly to produce differentiated progeny" is true or false.
