Answer:
The correct answer is - AABb/AaBb : aaBB/Aabb would be 1:1.
Explanation:
The cross between AaBb and AAbb will produce AB, Ab, aB, aB and Ab, Ab, Ab, Ab gametes respectively. These gametes from zygote and produce the two phenotypic character one with AABb/AaBb and aaBB/Aabb. The first phenotype would have both dominant traits while in others have only A dominant and B recessive in the phenotype of offspring.
Thus, the correct answer is - AABb/AaBb : aaBB/Aabb would be 1:1.
Scientists can track the movement of endangered species
I think it's C., carrying genetic information.
Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle.
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
Answer:
Crossing over
Explanation:
The onset of meiosis is characterized by shortening and thickening of genetic materials to form visible threads. Thereafter, homologous chromosomes pair up to a 4-chromosome structure known as tetrad.
The paired homologous chromosome then go ahead to exchange portions of chromosomes in a process known as <em>crossing over of genetic materials.</em>
