Regulation of opening and closing of stomata
The phenotype of antenna in crawfish depends on the protein amount in the antenna length. The offspring have different phenotype than their parent because of the amount of protein translated from each parent gene is determining in this.
The gene determines the amount of protein to be present in the antenna to determine its length.
Explanation:
Data given:
Two crawfish parent = medium length antennae, genotyoe Ll
One offspring = short antenna, genotype ll
one offspring = long antennae, genotype LL
The traits in offspring is shown as:
L l
L LL Ll
l Ll ll
The proportion of allele present in the gene determined the length of the antenna in crawfish.
The difference in length of the antenna in crawfish is due to the amount of protein for the phenotype present in the individual. The amount of protein to be expressed in the crawfish is given by both the parents. The tendency of protein expresed define the phenotype of antenna length.
<u>Answer</u>:
It is important for the chromosomes to condense during mitosis to facilitate chromosome movement.
<u>Explanation</u>:
The chemical called colchicine is found to be used during the process of mitosis, so as to freeze the cells, which can stop or prevent the movement of the chromosomes. This process is also essential for the faithful genome replication or transmission to those daughter cells. During the interphase cell division occurs but during the prophase the cell condensation is found to be happening. Before the process of the mitosis chromosomes are allowed to move and during this entangled and breaking were also noticed.
