I am not an expert in this field, but I am very interested and have researched to find an answer. I received some assistance from tlooto.com for this response. Could you please review the response below to see if it is correct?

In the context of Jackson Lab genotyping protocols, the term "Alternate (number)" refers to different versions or methods of genotyping for the same genetic modification. These alternates indicate distinct genotyping protocols tailored to specific experimental needs or variations in the genetic construct. For example, Pvalbalternate2 and Pvalbalternate7 suggest different genotyping strategies which may involve variations in primers, PCR conditions, or detection methods. This flexibility allows researchers to choose the most suitable protocol for their specific requirements, ensuring accurate and efficient genotyping [2][4]. For a comprehensive understanding of gene modification, exploring resources like Jackson Lab's protocols and related literature is beneficial [1][3].

first of all thank you for your answer and introducing this platform. I think you are right. i'll keep looking into it. Have a good day.

Ignore the answer from Park Sowon , it's AI-generated nonsense and the references aren't even for mouse genotyping.

Go to the Jax.org website and read about how to genotype cre-Lox mouse lines.

Good luck!

Thank you so much i'll look into it
