incross
Very LowTechnical/Scientific
Definition
Meaning
In genetics, to cross two inbred strains, or the organism resulting from such a cross.
A specific type of crossbreeding between closely related, genetically uniform lines to study inheritance or to produce organisms for research. It can also refer broadly to an internal or inward crossing.
Linguistics
Semantic Notes
Primarily used as a noun ('an incross') or a verb ('to incross'). It is a term of art in genetics, horticulture, and animal breeding. Not used in general language.
Dialectal Variation
British vs American Usage
Differences
No significant differences; the term is international scientific jargon.
Connotations
Neutral scientific connotation in both varieties.
Frequency
Extremely rare outside of specialized literature in both regions.

Examples
By Part of Speech
verb
British English
- The researchers decided to incross the two pure lines to study the single gene's effect.
- You must incross these strains for several generations to stabilise the trait.
American English
- To create a genetically uniform population, they needed to incross the lab mice.
- The protocol requires you to incross the parent plants and then analyze the F1 generation.
adjective
British English
- The incross progeny displayed remarkable uniformity in phenotype.
- They selected an incross line for the subsequent experiment.
American English
- The incross mice were used as the control group in the study.
- An incross breeding scheme was outlined in the methodology section.
Examples
By CEFR Level
- The term 'incross' is used by scientists who work with plants or animals.
- An incross produces offspring that are very similar to each other.
- The geneticists performed an incross between the two homozygous strains to isolate the variable.
- Unlike an outcross, which introduces genetic diversity, an incross aims to maintain a pure, uniform genetic line.
Learning
Memory Aids
Mnemonic
Think INbred lines CROSSed = INCROSS.
Conceptual Metaphor
A tightly controlled internal merger (like combining two pure samples).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'cross' meaning 'angry' (сердитый). It is not 'inner crossing' in a spatial sense. The closest Russian equivalent is 'инбредное скрещивание' или 'скрещивание инбредных линий'.
Common Mistakes
- Using it as a synonym for 'hybrid' (an incross is often genetically uniform, not hybrid).
- Confusing it with 'intercross' (crossing within a group) or 'outcross' (crossing to an unrelated line).

FAQ
Frequently Asked Questions
No, it is a highly specialized term used almost exclusively in genetics, biology, and selective breeding.
Yes, in technical contexts. For example, 'They will incross the two laboratory strains.'
An incross typically involves crossing two genetically similar or inbred lines, often resulting in uniform offspring. A hybrid usually involves crossing two genetically distinct lines or species, resulting in offspring with mixed traits (heterozygosity).
Only if they are involved in specialized plant breeding or genetics. Most gardeners would use terms like 'cross-pollinate' or 'breed' instead.
