Question
![**Genetic Cross and Recombination Frequency**
**Problem Statement:**
If the progeny of the cross aaBB x AAbb is testcrossed, and the following genotypes are observed among the progeny of the testcross, what is the frequency of recombination between these loci?
**Observed Genotypes:**
- AaBb: 135
- Aabb: 430
- aaBb: 390
- aabb: 120
**Instructions:**
Calculate the recombination frequency using the observed genotype data from the testcross. Determine which genotypes reflect parental types and which reflect recombinants, then use the formula for recombination frequency:
\[ \text{Recombination Frequency (RF)} = \left( \frac{\text{Number of Recombinants}}{\text{Total Number of Offspring}} \right) \times 100\% \]

Transcribed Image Text:The map distance between two genes R and S is 16%.
If you perform the following cross: RS/rs x rs/rs and have 100 progeny, how many of each of the following genotypes do you expect?
- RS/rs: 42
- rs/rs: 42
- Rs/rs: 8
- rS/rs: 8
