What breeding schemes can this tool plan?

The breeding scheme architect handles single allele crosses including conditional knockouts with Cre lox systems, reporter alleles, and humanized models. It calculates optimal breeding paths, expected genotype ratios, and estimates time to experimental cohorts. Contact our scientific team for multi-allele or complex mating schemes.

How does the tool calculate breeding pair numbers?

The calculator uses established statistical methods similar to published research tools, accounting for Mendelian inheritance ratios, strain specific litter sizes (C57BL/6 averages 6 to 8 pups), breeding efficiency (approximately 80%), and your target sample size requirements.

Can I save my breeding scheme?

Export your breeding plan as a PDF using the export button, or use the copy link button to share the page with collaborators. For a saved record of your project, request a consultation and our team will document your strategy.

What allele types does this tool support?

The tool supports nine allele types: conditional knockouts (floxed), conventional knockouts, Cre drivers (constitutive and inducible), reporters (fluorescent and LacZ), knockins (point mutation and cDNA), and humanized alleles. Enter your allele, set your target genotype, and the tool calculates the optimal breeding path.

How do I get help with my specific breeding project?

Request a project consultation to discuss your breeding scheme with our scientific team. We can help optimize your strategy, recommend appropriate Cre driver lines, and design model generation if needed. Consultation requests receive responses within one business day.

How the Breeding Scheme Architect Works

Planning single allele breeding schemes can be complex. This tool simplifies the process by automating Mendelian genetics calculations and identifying optimal breeding strategies.

This tool plans single allele crosses. For multi-allele or complex mating schemes, contact our scientific team for project-specific guidance.

STEP 1

Define Your Allele

Enter your targeted allele. This could be a knockout, Cre driver, reporter, or humanized allele. Specify your genotypes and chromosomal location.

STEP 2

Set Target Genotypes

Define the experimental and control genotypes you need for your study. Specify how many mice of each genotype are required and any sex requirements. The tool accounts for Mendelian ratios when calculating breeding numbers.

STEP 3

Generate Breeding Plan

The algorithm calculates the optimal sequence of crosses and maps the path from your starting material to study ready cohort size. View expected offspring ratios for different starting genotypes.

STEP 4

Export or Consult

Save your breeding plan as a PDF, share with collaborators, or request a consultation with our scientific team. We can help optimize your strategy, recommend Cre driver lines, or design model generation for your research.

Why Researchers Use the Breeding Scheme Architect

Visualize Your Breeding Path

See your entire breeding strategy mapped out generation by generation. Understand which crosses to prioritize and when you can expect to have experimental cohorts ready.

Optimize Resource Use

Calculate the number of breeding pairs and total mice needed to achieve your target sample sizes. Plan cage requirements and budget before starting.

Avoid Common Mistakes

The tool warns about embryonic lethal genotype combinations, germline Cre activity issues, and potential linkage problems that could complicate your breeding scheme.

Plan Before You Order

Use the breeding scheme architect before ordering model generation to understand post delivery breeding requirements and timeline to study ready cohorts.
