The fusion of two parents' genetic material is understood as sexual reproduction while asexual reproduction yields genetically similar offspring to the same parent.
<u>Asexual Reproduction:</u>
This way all the prokaryotes and other eukaryotes produce offspring. There are a variety of different asexual reproductive practices. These comprises of binary, fragmentation, and budding fission.
- The binary fission appears when a parent cell wants to split into 2 separate daughter cells of the same diameter. For an instance, protozoa reproduces in the same way.
- Fragmentation happens when a parent entity divides into small parts or fragments, and each segment grows into a recent organism. Starfish, that way replicate.
- Budding happens when a parent cell develops a bud close to a bubble. When growing and developing, the bud remains connected to the parent cell. This get detached from the parent cell when the bud is completely grown, and becomes a new entity. It is common in hydra and yeast.
<u>Sexual Reproduction:</u>
- A reproductive process which comprises haploid female gamete fusion, i.e. egg cell and haploid male gamete i.e. sperm cell.
- That implies they only include half the number of chromosomes contained in other species cells. A form of cell division named meiosis creates gametes.
- These gametes are fused at fertilization which results in the production of a diploid zygote having the chromosome double of gametes.
BioSafety Level (BSL) 3 labs,
perform work with indigenous or exotic agents that may cause serious or
potentially lethal diseases through the inhalation exposure. Biological Safety
Levels (BSL) are a sets of protections assigned to the activities that occur in
specific biological laboratories. BSL protects laboratory workers, the
surrounding environment and also the community.
Aneuploidy can result in the final daughter cell if the spindle fibers fail to pull a chromosome toward the pole as in case of non-disjunction.
Explanation:
Aneuploidy is a condition which arises when one or more chromosome is missing in the final daughter cells.
Non-disjunction refers to the failure of chromosomal or chromatid segregation or separation during cell division. This results in erroneous meiosis or mitosis leading to the formation of final daughter cells or gametes with an extra or missing chromosome. This condition is aneuploidy.
Failure of separation or segregation of:
- Homologous chromosomes occur in Anaphase I, affects four daughter cells.
- Sister chromatids during Anaphase II, affects two daughter cells
This failure of separation leads to aneuploidy chromosomal abnormalities like monosomy, trisomy, etc which can cause diseases like Down’s syndrome, Turner’s syndrome etc.
