- What will be the number of chromosomes in Turner's syndrome and Klinefelter's syndrome of an organism whose haploid number is 20? 39 in Turner's syndrome and 41 in Klinefelter's syndrome 41 in Turner's syndrome and 39 in Klinefelter's syndrome 19 in Turner's syndrome and 21 in Klinefelter's syndrome 38 in Turner's syndrome and 41 in Klinefelter's syndromeIn Drosophila (fruit flies), jammed wings (J), daughterless (da), curly wings (Cy), star eyes (S), and a black body (b) are determined by genes located on the same chromosome. Gene Combination Recombination Frequency J and Cy 34.9 J and da 1.7 S and Cy 4.8 Cy and b 42.4 S and da 38 b and S 47.2 What is the map unit distance between b and da?Answer map unitsRecord your answer as a value rounded to one decimal place.By conducting testcrosses, researchers have found that the sweetpea has seven linkage groups. How many chromosomes would youexpect to find in leaf cells of the plants?
- A liver cell in a crocodile contains 32 chromosomes. Which of the following correctly shows the haploid cell in a crocodile and the number of chromosomes expected to be found in a haploid cell? A B C D sperm cell, 32 chromosomes brain cell, 16 chromosomes egg cell, 16 chromosomes muscle cell, 32 chromosomes26 of 40 21 22 23 24 25 26 27 28 29 30 Miller, Timia Polyploid plants form as a result of a beneficial mutation that often makes them larger and stronger than diploid plants. These plants form when a complete set of chromosomes fails to separate during meiosis creating plants with extra chromosomes. What type of mutation has this result? O frameshift O nondisjunction substitution O translocation https://student.masteryconnect.com/%3 9/0Species A and B are closely related. Species A has 2n = 12 chromosomes, and species B has 2n = 16 chromosomes. How many chromosomes would be found in the somatic cells of an allotetraploid? 56 38 20 28 14

- At the end of mitosis in Aedes aegypti, each of the daughter cells will have chromosomes; however, at the end of meiosis, each daughter cell will end up with chromosomes.In 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?Map distances were determined for four differentgenes (MAT, HIS4, THR4, and LEU2) on chromosome III of the yeast Saccharomyces cerevisiae:HIS4 ↔ MAT 37 cMTHR4 ↔ LEU2 35 cMLEU2 ↔ HIS4 23 cMMAT ↔ LEU2 16 cMMAT ↔ THR4 20 cMWhat is the order of genes on the chromosome?
