# Determine if input sequence is a bimera of putative parent sequences.

### Description

This function attempts to find an exact bimera of the parent sequences that matches the input sequence. A bimera is a two-parent chimera, in which the left side is made up of one parent sequence, and the right-side made up of a second parent sequence. If an exact bimera is found TRUE is returned, otherwise FALSE. Bimeras that are one-off from exact are also identified if the allowOneOff argument is TRUE.

### Usage

### Arguments

`sq` |
(Required). A |

`parents` |
(Required). Character vector. A vector of possible "parent" sequence that could form the left and right sides of the bimera. |

`allowOneOff` |
(Optional). A |

`minOneOffParentDistance` |
(Optional). A |

`maxShift` |
(Optional). A |

### Value

`logical(1)`

.
TRUE if sq is a bimera of two of the parents. Otherwise FALSE.
