2. Please give answers with detailed explanations. preferentially done by hand or on computer. Need ASAP and will rate ASAP. part ll-Free Response/Short Answer 1. (5 pts) In a certain species of mosquito, bristies on the head can be curved, straight or spiraled. In addition, ne loci, each locuS curved bristles, some mosquitoes may lack bristles. These four phenotypes are determined by three gene lodh with just two alleles. At the first locus, mosquitoes with at least one dominant allele C have whereas C+iC+ individuals have straight bristles. But to have either curved or straight a second locus must be recessive (h/h). Individuals with a dominant H allele have spiraled regardless of what alleles are present at the first locus. Finally, to have bristles, the present at the third locus. All a/a individuals are lack bristles altogether, regardless of the straight bristles, both alleles at bristles allele a+ must be less of the combination of alleles at the other two loci. The three loci are autosomal and unlinked A male mosquito with straight bristles was offspring were as follows mosquito with straight bristles was mated with a female with the genotype CiC+, H/h; ala. The 80 spiral bristles 40 straight bristles 40 curved bristles 160 no bristles. Total: 320 A. (2 pts) What is the phenotype of the female parent? B. (3 pts) What is the genotype of the male parent?

Explanation / Answer

the allele present are ;

C - curved hair ,dominant

C+ -recessive ,straight hair

H -spiraled hair - dominant

h -recessive of spiraled

a/a+ -lack of hair { seen at third locus }

1. phenotype of the female mosquito ;

the phenotype of the female will be curved hair which is a dominant allele ,located at the first locus of the gene .

2. Genotype of the male parent ;

c+/c+ ; h/h ; a/a+ ,

c+ represent the straight hair which is a recessive allele ,a no hair , h ,recessive spiraled hair
