The punnett square shows alleles for hairline type among one parent and the possible allele frequencies among the children. the dominant form of this trait is a widows peak (p), and the recessive form is a straight hairline. the alleles for one parent are missing. punnett square for hairline type p p pp pp pp pp what are the alleles for the missing parent?

explanation:

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

bacterium is not correct

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
