In Jurassic Park, dinosaurs were created from dinosaur DNA extracted from fossils. Do you think this is science friction or is i
exis [7]
I think it might be possible because they took the nucleus from a sheep and put it inside a sheep embryo and it made an exact clone of the sheep.If they could make a nucleus that could handle the DNA of the dinosaurs and have the nucleus function properly and have the embryo grow properly then it might be possible for them to create dinosaurs.

Assume that a cross is made between AaBb and aabb plants and that the offspring occur in the following numbers: 106 AaBb, 48 Aab
Elenna [48]

Answer:

linkage with approximately 33 map units between the two gene loci

Explanation:

If two genes are not linked, number of recombinants and parental offspring will be equal. Here it is clearly visible that recombinants are less than parental offspring hence the genes are linked. Given, the offspring are in following numbers:

AaBb = 106 = Parental

aabb = 94 = Parental

Aabb = 48 = Recombinant

aaBb = 52 = Recombinant

Recombination frequency = (Number of recombinants/ Total progeny) * 100 = (100/300) * 100 = 33.33 %

1% recombination frequency= 1 map unit of distance between the two gene loci. So here the distance between the two gene loci is approximately 33 map units.

Hence, these results are consistent with linkage with approximately 33 map units between the two gene loci
