Answer:
50% of mice would be grey (GG [phenotype is grey and genotype is grey])
50% of mice would be grey and brown (GB [phenotype is grey and brown])
GG is complete dominance
GB is codominant
Answer:
1. 128
2. 16,384
Explanation:
Imagine there were two pairs of chromosomes:
A paired with B
C paired with D
A gamete could have the following combinations:
A + C
A + D
B + C
B + D
Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities
With seven pairs of chromosomes, there are (2⁷) possibilities. 2⁷ = 128
For a zygote produced by two barley parents, there are two gametes fused. So we must multiply the number of combinations for each gamete. Therefore, number of possible genetic combinations is 128 x 128 = 16,384
B. Solar flares
The auroras are caused by space dust particles reflecting and mixing with earth’s atmosphere
Answer:
People, not machines, perform fingerprinting. They do search for a particular amount of matches before taking into account a whole match.
Explanation:
Answer:
The correct answer is: translesion.
Explanation:
Also called DNA polymerase V, the translesion polymerase is responsible for the repair of the DNA in prokaryotes like Escherichia coli.
These special enzymes repair DNA lesion during DNA replication. If the enzyme fails, the damage in the DNA can lead to the death of the cell.
Replication in prokaryotes is much more prone to errors than replication in eukaryotes, one of the reasons being this polymerase not being as effective as the polymerase in charge of repairing eukaryotic DNA, the DNA polymerase beta.
