Answer:the probability of their first two offspring being aa is 0.25
Explanation:
Because their are 4 possible genotypes for the offsprings
AA Aa Aa aa
And the probability of aa is 1/4
The organelle that temporarily breaks apart so that the DNA can divide up is the nucleus. Nucleus store most of the cell's DNA it is responsible for carrying genetic information. It is also responsible for generating genetic expression to ensure the proper activities of the entire cells.
Answer:
BbxBb.
Explanation:
If Bb gene is crossed with Bb, the offspring is produced with normal hearing because both the genes are recessive in which the deafness gene hide and the hearing gene is dominant so the offspring can hear sounds clearly. The dominant A gene is responsible for deafness and we can see the offspring BbxBb in which no dominant gene is present. The other three offspring are deaf because of the presence of dominant A gene in their genetic makeup.
Secondary since plants/animals already lived there, but got killed/driven out of the area they lived/thrived in/on.
Although there is no attachment, the best answer would be option B.
DNA replication occurs in opposite directions along a strand of DNA.
The leading strand is replicated continuously in the 5' to 3' direction towards the replication fork.
The lagging strand is replicated discontinuously in the 5' to 3' with segments of DNA known as Okazaki fragments.
