6. Marty Martian recently met Melissa Mercury online.
Marty is heterozygous for his purple body color, but Mellisa is blue.
Create a Punnett square to show the possibilities that would result if Marty and Melissa had children.
List the possible genotypes and phenotypes for their children. What are the chances of a child with a purple body?
What are the chances of a child with a blue body?

Drag each tile to the correct box. arrange the phases of mitosis in the correct order. 1 (condensation of chromosomes) 2 (separation of chromosomes) 3 (formation of spindle fibers) 4 (alignment of chromosomes in the center of the cell) 5 (pinching of the cell membrane)

If all prokaryotes on earth suddenly vanished, which of the following would be the mostlikely and most direct result? a) the number of organisms on earth would decrease by 10—20%.b) human populations would thrive in the absence of disease.c) bacteriophage numbers would dramatically increase.d) the recycling of nutrients would be greatly reduced, at least initially.e) there would be no more pathogens on earth.

Dna sequences in many human genes are very similar to the sequences of corresponding genes in chimpanzees. the most likely explanation for this result is that:
