Homework Answers
Answer:
Mangled leaf, limp stem, prickly fruit
Explanation:
Least common phenotypes are double crossovers. If we flip the phenotype of double crossovers, we can get the order of three genes.
Double crossovers:
mangled leaves- prickly fruit – normal stem
normal leaves – normal fruit – limp stem
Wild type progeny:
In the given heterozygote, Mangled leaf, prickly fruit, limp stem is present. Due to change of limp stem with normal stem, the wild progeny would be produced. Hence, the middle gene is limp stem.
mangled leaves – limp stem - prickly fruit
normal leaves – normal stem- normal fruit

Explain Both and Answer Thank You
The eyeless trait is recessive in Drosophila. One of the offspring of a cross between heterozygote (Ee) parents has eyes. How would you determine whether this fly is homozygous (EE) or heterozygous (Ee)? Cross it with a fly that has eyes but an unknown genotype Cross it with a heterozygous fly Cross it with an eyeless fly Cross it with a fly that has eyes and an EE genotype Question 23 3 pts A...

Question 23 3 pts A plant that is homozygous recessive for mangled leaf and prickly fruit (mmpp) is crossed with the double heterozygote (MmPp), resulting in 1047 offspring: 472 with mangled leaves (mP), 453 with prickly fruit (Mp), 63 wild type (MP), and 59 with mangled leaves and prickly fruit (mp). From these data, you can conclude that o The M and P genes are located 11.7 CM apart o The M and P genes...

A wild-type trihybrid soybean plant is crossed to a pure-breeding soybean plant with the recessive phenotypes pale leaf l, oval seed (r), and short height (t). The results of the three-point test cross are shown in the table. Traits not listed are wild type. A) Place the alleles in their correct gene order. Use L, R, and T to represent dominant alleles and l, r, and t for recessive alleles. L-T-R L-R-T T-L-R B) Calculate the recombination fraction between T...

A tomato plant heterozygous for stem color and fasciation (the dominant alleles linked on the same chromosome) is pollinated by a plant heterozygous for stem color and homozygous recessive for fasciation (that is nonfasciated). 29. What alleles will the sperm carry?_ What alleles will the eggs carry? 30. What are the genotypes of the progeny? What are the phenotypes of the progeny? 31. If the dominant alleles for stem color and fasciation are commonly located on the same chromosome, how...

Drosophila females of wild-type appearance but heterozygous for three autosomal traits are mated to males that are homozygous recessive for the three traits. The three autosomal recessive traits are glassy eyes (g), coal-colored bodies (c), and striped thoraxes (t). The three dominant traits are red eyes (g+), gray bodies (c+) and solid thoraxes (t+) (remember, the wild-type allele has a + after it). You examine 1000 progeny of the above cross and they have the following phenotypic classes: 265 g+c+t+ 275 gct 120 g+ct...
