Answer:Lisa goes in the first box Andrea’s goes in the last box there goes in 2 box and the last one goes in the third box
Explanation:
Answer:
Dust bowl resulted from extreme drying and loosening of the soil that resulted in soil erosion by wind. Thus, it can be related that poor agricultural practices like over plowing , over grazing and leaving the land barren are human activities that must have contributed to the dust bowl.
Explanation:
- Dust bowl is referred to a period in early twentieth century when the the American and Canadian prairies faced severe dust storms.
- These dust storms resulted from severe drought and failure of practices to prevent soil erosion.
- Several people and livestock died as a result of choking.
- Over plowing, removal of top soil and small grasses exposed the soil to eroding winds and caused the dust storms.
We first check the first parent's possible alleles: OT, Ot, OT, Ot. (Combinations of the 2 O-alleles and T-alleles given).
A similar process is used for the second: OT, Ot, oT, ot
Genotypes: Check the attachment. We combine the alleles from each parent (for example, Ot + oT = OoTt). We do this for all 16 combinations.
Genotype Likelihoods: We count each of the possible results and tabulate the number of times each appears, and divide by the total number of combinations (16).
OOTT: 2/16 = 1/8 = 0.125
OOTt: 4/16 = 1/4 = 0.25
Oott: 2/16 = 1/8 = 0.125
OoTT: 2/16 = 1/8 = 0.125
OoTt: 4/16 = 1/4 = 0.25
Oott: 2/16 = 1/8 = 0.125
Phenotypes: Check attachment. Based on the genotypes, use the dominant gene if at least one is dominant (Ex. Oo = O, oo = o)
Phenotype Likelihoods: We count the number of each possibility, only 2 of which are present: OT and Ot, then divide by the total number of combinations, which is 16.
OT: 12/16 = 3/4 = 0.75
Ot: 4/16 = 1/4 = 0.25
