Answer:
Deletion mutation refers to the deletion of a sequence of DNA or a part of a chromosome.
It can vary from a deletion of a single nucleotide to an entire chromosome.
It is usually caused by errors during replication, errors during crossing over, and translocation.
Deletion can cause various genetic disorders in human, for example, Williams syndrome (deletion of genetic material from chromosome 7), cystic fibrosis (2/3rd cases are caused by deletion of three nucleotides from chromosome 7), cri du chat syndrome (due to deletion mutation occur in chromosome 5) et cetera.
It can also lead to infertility in males.
In extreme cases, it can also lead to the death of an individual.
The answer is A, the bladderwort eats the tadpoles tail:)
Mutation is a source but it is not the main source after it comes recombination in which 2 chromosomes with “normal” survival are taken from natural population of Drosophila and combined. Then comes immigration of genes in which the new chromosome mix in with different gene frequencies.
Meiosis is a type of cell division which occurs in gonades to produce gametes.After meiosis number of chromosomes become half.
