X-linked disorder is a recessive autosomal disorder, which means that
There is a 1 in 4 chance (25%) of having a child who is unaffected.
There is a 1 in 4 chance (25%) of having a child who is affected by the condition. These children have two copies of the gene that do not work correctly.
There is a 1 in 2 chance (50%) of having a child who is a carrier of the condition. These children have one working copy of the gene and one copy of the gene that does not work correctly.
Answer:
Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Explanation:
All the three options given can cause checkpoint genes to interrupt cell division.
Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.
Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.
Every species has different timespans. Some butterflies live 6 months, other live 7 years. However, most of their time they are caterpillars or are in a coccoon. Up to 6 years
