Answer:
Given Data:
- F1 individual genotype: (ab)
- Offspring data:
- /ab: 10
- ab/ab: 10
- a/ab: 40
- b/ab: 40
To determine the configuration of the F1 individual (cis or trans), we need to analyze the offspring data and apply the principles of genetic inheritance.
1. Understanding Cis and Trans Configurations:
- In genetics, the terms "cis" and "trans" refer to the arrangement of alleles on homologous chromosomes.
- In the cis configuration, the two alleles of a gene are located on the same homologous chromosome (e.g., a/a and b/b on one chromosome).
- In the trans configuration, the two alleles of a gene are located on different homologous chromosomes (e.g., a/b on one chromosome and a/b on the other chromosome).
2. Analyzing the Offspring Data:
- From the given data, we can observe the following offspring counts:
- /ab: 10
- ab/ab: 10
- a/ab: 40
- b/ab: 40
3. Interpreting the Offspring Data:
- The presence of /ab individuals indicates that the F1 individual is heterozygous for both alleles (a and b).
- The presence of ab/ab individuals indicates that the F1 individual is homozygous for both alleles (a and b).
- The presence of a/ab and b/ab individuals indicates that the F1 individual has one of the alleles on one chromosome and the other allele on the other chromosome.
4. Predicting the Configuration:
- Based on the offspring data, we can conclude that the F1 individual has both alleles (a and b) on different homologous chromosomes (trans configuration).
- This is evident from the presence of a/ab and b/ab individuals, which indicates that the alleles are present on different chromosomes.
5. Final Answer:
- The configuration of the F1 individual is trans configuration (Option B).
- There is no evidence to suggest that the alleles are located on the same chromosome (cis configuration), as there are no individuals with both alleles on one chromosome.
In summary, the test cross data suggests that the F1 individual has the trans configuration, with alleles (a and b) located on different homologous chromosomes.
Given Data:
- F1 individual genotype: (ab)
- Offspring data:
- /ab: 10
- ab/ab: 10
- a/ab: 40
- b/ab: 40
