The recessive gene sh produces shrunken endosperm in corn kernels and its dominant allele sh+ produces...
Homework Answers
Answer:
a).
Hint: parental combinations are always large numbered than recombinant progeny in linkage.
So...
sh c/sh c (shrunken, colorless) x (plump, colored) sh+ c+/sh+ c+ ------ parents
sh+ c+ / sh c (plump, colored)---- F1
b).
The two genes are linked in cis configuration.
c).
Recombination frequency = (recombinants progeny / total progeny)100
RF = (149+152/8368)100
= 3.6%
RF (%)= distance between genes (m.u)
Distance between sh and c= 3.6 m.u.

Researchers cross a corn plant that is pure-breeding for the dominant traits colored aleurone (C1), full kernel (Sh), and waxy endosperm (Wx) to a pure-breeding plantwith the recessive traits colorless aleurone (c1), shrunken kernel (sh), and starchy (wx). The resulting {rm F}_{1} plants were crossed to pure-breeding colorless,shrunken, starchy plants. Counting kernels from about 30 ears of corn, the results are reported in the table.Kernel Phenotype NumberColored, shrunken, starchy 116Colored, full, starchy 601Colored, full, waxy 2538Colored, shrunken, waxy 4Colorless, shrunken...

Three genes with recessive mutant phenotypes are located on the same chromosome in maize: waxy endosperm (wx), shrunken endosperm (sh), and virescent seedling (v). A plant with all three mutant phenotypes is crossed with a true-breeding, wild-type plant. Resulting F1 plants are then backcrossed to the parental mutant line to produce the following progeny: Waxy Shrunken Virescent Number wx sh + 89 + + v 92 + + + 1482 wx sh v 1475 + sh + 480 wx +...

i need to know how this was done.
Researchers cross a com plant that is pure-breeding for the dominant traits colored aleurone (C1), full kernel (Sh), and waxy endosperm (Wx) to a pur breedin ant with the recessive traits colorless aleurone (c1). shrunken kernel (sh), and starchy (wx). Review The resulting Fi plants were crossed to pure-breeding colorless, shrunken, starchy plants. Counting kernels from about 30 ears of corn yields the data shown in the table.

1) (3 pts) The following two recessive genes are known for corn: brittle endosperm (b) and glossy leaf (g). Two true-breeding plants with contrasting phenotypes are crossed (both plants are homozygous for both genes). The Fi offspring are all wild type.

In a certain plant, a dominant allele for one gene, R, produces round fruit and the recessive allele, r, produces oblong fruit. A dominant allele of a second gene, Y, produces yellow flowers and the recessive allele, y, produces white flowers. The two genes are linked on chromosome IV. A plant ( ry / ry ) with normal chromosomes is crossed to a plant (R Y/R Y) homozygous for a reciprocal translocation between chromosomes IV and VIII. The presence of...

9.18 In corn, a colored aleurone is due to the presence of an R allele; r/r is colorless. Another gene controls the color of the plant, with g/g being yellow and G_ being green. A plant of unknown genotype is test-crossed, and the following progeny plants were obtained. Colored green 89 Colored yellow 13 Colorless green 9 Colorless yellow 92 What was the phenotype and genotype of the plant used for the test cross? What were the phenotypes of the...

A purebred sweet corn plant that produces purple and smooth kernels pollinates a purebred plant that produces yellow and wrinkled kernels. When the F1 was testcrossed, four types of kernels on the cobs were observed in almost equal proportions: purple and smooth, purple and wrinkled, yellow and smooth, and yellow and wrinkled. Which of the following statement(s) are TRUE? I. The F1 plants can only produce purple and wrinkled kernels when selfcrossed. II. If the parent that produces yellow and...

In hogs, and allele that produces a white belt around the animals body (W) is dominant over its allele for a uniformly colored body (w). The dominant allele of another gene (F) produces a fusion of the two hoofs on each foot. Suppose a uniformly-colored hog homozygous with fused hoofs is mated with a normal-footed homozygous for the belted character. what are the genotypes of the parents? belted parent: Uniformly-colored parent: What are the genotypic and phenotypic ratios in the...
