The same number <span>chromosomes are there in a maize egg cell nucleus as compared to a maize pollen cell nucleus</span>
X, right trigger, left trigger, left bumper, left, left, Y
Answer:
The answer is D.
Explanation:
The example given in the question is an example of gene flow which can be described as the movement of specific genes from the the gene pool population to population.
The act of catching the bigger fish and letting the smaller ones escape is changing the gene pool of the North East Arctic Cod and causing the next generations to have smaller and smaller sizes which is given as the genetic variation decrease due to gene flow.
I hope this answer helps.
Answer:
b. During replication there is both a leading strand and a lagging strand
.
c. Each replication bubble has two replication forks.
Explanation:
Eukaryotic chromosomes have multiple origins of replication to replicate the long chromosomes at a higher rate.
The two DNA strands have opposite polarity, that is, 5' end of the one DNA strand is present opposite to the 3' end of the other DNA strand. DNA replication occurs only in 5' to 3' direction and the direction of the movement of the replication fork is also 5' to 3' direction.
To allow the DNA replication in 5' to 3' direction on both strands, one strand is replicated discontinuously in the direction opposite to the movement of the replication fork.
The discontinuously replicated strand is lagging strand while the other one is the leading strand.
DNA replication in eukaryotes occurs bidirectionally as two replication forks are formed at each replication bubble, one at each end of the replication bubble.
The presence of multiple origins of replication and the bidirectional process allows the replication of large eukaryotic DNA at a considerable fast speed.
Answer:
0%
Explanation:
To solve this, we can use a Punnett square.
R R
R RR RR
W RW RW
From this cross, there are two possible genotypes: RR and RW. The genotype RR results in a red flower, and the genotype RW results in a pink flower. Since the genotype WW is not possible with this cross, none of the offspring are expected to have white flowers.
