Answer:
allopolyploidy
Explanation:
Polyploidy is the condition by which a cell might have more than two chromosome sets that form homologous pairs. It might occur due to a failure or abnormality in cell division.
Autopolyploidy
Refer to a type of polyploidy in which an organism has more than two copies of homologous chromosomes. It results from the duplication of a group of chromosomes of the same species. Autopolyploid individuals have <u>at least three groups of homologous chromosomes</u>. Autopolyploidy is produced by the<u> gamete fusion of the same progenitor - same species</u>-, duplicating the number of chromosomes of diploid species. The autopolyploid cell has groups of homologous chromosomes. Autopolyploidy is produced mainly due to non-disjunction during meiosis.
Allopolyploidy
Refer to another type of polyploidy in which species have more than three sets of chromosomes in their cells. Allopolyploidy <u>occurs when two different species mate</u>, leading to the fusion of gametes that belong to different species and produce a new hybrid. The chromosomic complement has more than two copies of chromosomes. The hybrid is infertile with the parental species. The allopolyploid cells have chromosome groups that are not homologous.
In the exposed example two different species mate and produce a hybrid species.
Answer:
silk moth are animals whose cocoons are used to make silk.
Explanation:
silk is a fibre or we can say a luxurious and expensive fibre which is used in making silk clothes. They are highly soft and smooth!
Answer:
yes. it's important to save the species that are closer to extinction first. the more critically endangered, the more important it is to save.
Explanation:
Answer:
The given blank can be filled with interferons.
Explanation:
The signaling molecules or the proteins that get discharged by the cell infected by the virus to protect the adjacent cells by stimulating a safeguarding defense mechanism are termed as interferons.
The mentioned proteins obstruct the proliferation of viruses and thus helps the cell in getting rid of the infection. These molecules also assist in stimulating the macrophages and the natural killer cells.
