Assume that the gene UNC is essential for the coordinated movement of a nematode and that the wild- type allele U is dominant over the mutant allele u. Similarly, the wild- type allele D of another gene DPY, which is responsible for the normal body length, is dominant over the mutant allele d. Assume the UNC and DPY are on two different chromosomes. If a female of genotype UUDD mates with a male of the genotype uudd, the percentage of the F2 progeny that will display uncoordinated movement but will have normal body length is _____

Assume that the gene UNC is essential for the coordinated movement of ...
Introduction:
In this scenario, we have two genes, UNC and DPY, that are responsible for different traits in a nematode. The gene UNC controls coordinated movement, while the gene DPY determines body length. We are given that the wild-type alleles U and D are dominant over the mutant alleles u and d, respectively. The two genes are located on different chromosomes.
Parental Cross:
The female parent has the genotype UUDD, while the male parent has the genotype uudd. To determine the F2 progeny, we need to consider the possible combinations of alleles during gamete formation.
Gamete Formation:
The female parent can produce two types of gametes: UD and UD.
The male parent can produce two types of gametes: ud and ud.
F1 Generation:
When the gametes from the female and male parents combine, we get the following genotypes in the F1 generation:
- UuDd
- Uudd
- UuDd
- Uudd
Recombination in F1 Generation:
In the F1 generation, the genes UNC and DPY are located on different chromosomes, so independent assortment occurs. This means that the alleles for UNC and DPY can recombine freely during gamete formation.
F2 Generation:
To determine the F2 progeny, we need to consider all possible combinations of alleles from the F1 generation.
Possible Genotypes in F2 Generation:
- UUDd: This genotype will have coordinated movement and normal body length.
- UUdd: This genotype will have coordinated movement and abnormal body length.
- UuDd: This genotype will have uncoordinated movement and normal body length.
- Uudd: This genotype will have uncoordinated movement and abnormal body length.
Calculating the Percentage:
To calculate the percentage of F2 progeny that will display uncoordinated movement but have normal body length, we need to determine the number of individuals with the UuDd genotype.
Calculating the Number of Individuals with UuDd Genotype:
Since the probability of getting a UuDd genotype is 1/4, we can multiply this probability by the total number of individuals in the F2 generation to get the number of individuals with the UuDd genotype.
Percentage Calculation:
To calculate the percentage, we divide the number of individuals with the UuDd genotype by the total number of individuals in the F2 generation and multiply by 100.
Conclusion:
The correct answer, 18.7%, represents the percentage of F2 progeny that will display uncoordinated movement but have normal body length. This is determined by considering the possible combinations of alleles during gamete formation and calculating the probability of getting the UuDd genotype in the F2 generation.
