This is a positive mutation, because the offspring will survive longer to reproduce. Their offspring will then carry the same genes passing it off to their offspring. The other color mice that did not blend into its environment will soon be extinct, leaving only the mice that can blend in.
Answer:
True
Explanation:
Let the allele for green color of pods be G
and the allele for yellow color of pods be g
Phenotype of true breeding parent with green colored seeds is GG
Phenotype of true breeding parent with yellow colored seeds is gg
In F1 cross
GG mates with gg
Genotype of offspring - Gg
Phenotype of offspring - Green seed
Since the offspring has both the allele for green and yellow seeds color but yet only green is expressed. This indicate that green allele dominated the expression of yellow allele thus, it can be concluded that green seed pods were dominant over yellow seed pods.
Answer: D. Extinctions occur at higher rates during times of ecological stress when populations and species are poorly adapted.
They made the cell theory, concluding that all living things are made of cells.
