Three different homozygous strains of corn that produced ears with white kernels were crossed to each other. In each cross, the F1 plants were all red. When F1 plants are crossed, the F2 offspring show a distribution of 9 red: 7 white plants: parents F1 F2 white 1 x white 2 red 9 red: 7 white white 1 x white3 red 9 red: 7 white white2 x white3 red 9 red: 7 white How many genes are involved in determining kernel color in these strains

Based on anatomical similarities, to which modern animal is dr. digger’s creature most closely related?

The phylogenetic tree illustrates the relationship between humans and our closest living relatives. the tree was based on biochemical comparisons, including dna and amino acid sequences. according to the biomolecular data, we could infer that a) the four organisms do not have a common ancestor. b) humans are more closely related to chimps than any other apes. c) chimps are more closely related to gorillas than they are to humans. eliminate d) there is no evidence if any relationship between the four branches on the tree.

This is the interaction of two organisms where one is and the other is neither nor harmed.
