• How can we test the origin of life hypothesis “the Spontaneous Abiotic Origin”?

which of the primate traits do you think that you could live without and why? How would you psychologically and behaviorally compensate for the loss of this trait?

Your response should be at least one page ( I will give best ratings)

AA DD individuals were crossed to aa dd individuals. The F1 generation was then testcrossed to aa dd individuals. The resulting individuals had the following genotypes: 903 individuals with the genotype Aa Dd, 897 individuals with the genotype aa dd, 98 individuals with the genotype Aa dd, 102 individuals with the genotype aa Dd.

1. Are the genes (A and D) on the same chromosome or different chromosomes? (Calculate the expected number of progeny if they were on different chromosomes and compare.)

A. Same chromosomes

B. Different chromosomes

C. Can't be determined

2. If A and D are on the same chromosome, how far apart are they in Map Units. (Answer in a number - without units, if they are not on the same chromosome, answer 0).
