You are studying 5 genes: a, b, c, d, and e. In an attempt to map them, you perform a series of two-point crosses with the results listed below. Select the appropriate gene order based on the results of your experiment. a-b = 20 map units; a-c = 16 map units; a-d = 12 map unit; b-d = 8 map units; b-e = 4 map units; c-d = 28 map units; c-e = 40 map units; d-e = 12 map units. Group of answer choices 1)e-b-a-c-d 2)e-b-d-a-c 3)a-c-e-b-d 4)a-b-c-d-e

When you are visiting the local pet store you start talking to them about their Ceti alpha-5 eel colony. They tell you that some eels have red antennas, some have white antennas, and some have pink antennae. Whenever you cross an eel with red antennae to an eel with white antennae you only recover eels with pink antennae. If you assume antennae color is under the control of one gene and you cross two eels with pink antennae what would you predict would be the genotypes and phenotypes of the progeny? How would you explain these results? (Describe why the expected results from ‘a’ would happen.)
What would be the gene map for the following genes with known recombination frequencies? D and A is 5.1 cM, A and C is 15.8 cM, A and B is 7.8 cM, C and D is 10.7 cM, and C and B is 8.0 cM.
The gel image below shows 7 alleles, let’s call them 1-7 in order of size, with 1 being the largest and 7 being the smallest. In this sample of 11 individuals, how many times does allele 5 appear?
In Figure 5-15, how are each of the following genotypesproduced?a. F+ a− c. F− a+b. F− a− d. F+ a+
You conduct a series of two-point mapping crosses involving five genes located on chromosome III and obtain the following percentage of recombinant offspring: h-cu eyg-h eyg-cu rai-eyg rai-h rai-cu th-cu th-h th-eyg th-rai 23.5% 9.0% 14.5% 18.5% 9.5% 33.0% 6.8% 16.7% 7.7% 26.2% The rai gene is at the near end of the chromosome. Gene th is between which two genes? A. eyg and cu B. rai and cu C. h and cu D. rai and h
Eye colors are passed down through generations, but sometimes genetic variations can lead to surprising results in eye colors (dark eye color, still rocks!?) Some examples are found below. Is there truth behind the following? Provide explanations for your answer. Two parents with blue eyes cannot have a brown-eyed child and vice-versa. Eyes with more than one color stems from parents with two different eye colors. People with violet eyes are mutants. People with red or pinkish eye color can have dark-eyed parents.
You perform a cross between two plants, one MmPp and one mmpp, and obtain offspring with the following phenotypes: 42 MP; 374 Mp; 367 mP; 27 mp. What can you conclude from these data? Group of answer choices The M and P genes are on different chromosomes The recombinant progeny are mP and Mp The M and P genes are far apart on the same chromosome The recombinant progeny are MP and mp
This research exploited the principles of Mendelian genetics combined with the MCR technique to genetically manipulate fruit flies. Now, suppose you do a similar experiment. You perform two crosses: one that allows for Mendelian patterns of inheritance, and another that uses MCR with CRISPR-Cas9 to genetically edit the eye color of fruit flies. In fruit flies, the gene for eye color is located on the X chromosome. Red eyes (wild type, w+) are dominant to white eyes (mutant, w-). Let’s see how well you can predict genotype and phenotype ratios resulting from the two crosses. Genetic cross 1 (without MCR): Cross between a white-eyed male and a homozygous red-eyed female. Genetic cross 2 (with MCR): Cross between an MCR-element (carries the CRISPR-Cas9 construct) white-eyed male and a homozygous red-eyed female. Keep in mind, this technology converts a heterozygous genotype to a homozygous recessive genotype. Drag the labels to the table to fill in the genotypic and phenotypic ratios.
Part A: If the two genes are 30 mu apart and the plant is (AB/ab), what proportion of gametes from a single plant will be AB? Enter your answer as a decimal to three places (for example: 0.120). Part B: If the two genes are 30 mu apart and the plant is (AB/ab), what proportion of gametes from a single plant will be Ab? Part C: If the two genes are 30 mu apart and the plant is (AB/ab), what proportion of gametes from a single plant will be aB? Part D: If the two genes are 30 mu apart and the plant is (AB/ab), what proportion of gametes from a signal plant will be ab?
Scientists wanted to determine what molecule held the 'gene'. If they did a study in which a cell was infected by a virus, which part of the virus actually caused the infection inside the cell? Group of answer choices DNA ribosome protein RNA 2. When Mendel crossed in his P generation a yellow-seeded and green-seeded pea plants, all the offspring were yellow seeded. When he took these F1 yellow-seeded plants and crossed them with the original yellow-seeded plant from the P generation, what genotypic ratio was expected? Group of answer choices 1:2:1 3:1 1:1:1:1 1:1
