Earth would basically look like the Moon; minus the craters, of course. This is because with no atmosphere to hold all of the Oxygen near the surface, all life would die off fairly quickly.

Use the probability method to calculate the genotypes and genotypic proportions of a cross between AABBCc and Aabbcc parents.

lora16 [44]

For this, you need to use Punnett squares.

You know the genotype of the parents, and for the cross, you need to separate into two alleles, both genes.

AABBCc divided like ABC and ABc.

Aabbcc divided like Abc and abc.

Now you can cross them, and all probabilities will be:

AABbCc, AaBbCc, AABbcc and AaBbcc

So, you could say 25% of the offspring will be AaBbCc, 25% AaBbcc, 25% AABbCc, and 25% AABbcc

Korolek [52]
