Explanation:

While working in a laboratory it is very important to ensure that all safety measures are being followed otherwise it is possible that an accident in the laboratory can lead to harmful effects to a person.

For example, while heating a test tube we should use tongs so that our hand do not burn or feel the heat.

Also, check the apparatus carefully before using them to check if there are any chips or not.

Hence, we can conclude that steps to ensure laboratory safety during the experiment you carried out are as follows.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
