Question
Chapter 5, Problem 17P
Summary Introduction
To analyze:
The expected frequency for given gametes (a to d) by referring to a table.
Dihybrid genotype | Recombination frequency | Gamete genotype |
DE/de | 8% | De |
AD/ad | 28% | ad |
DEF/def | E – F 24% D – E 8% | dEf |
B - D 18% D – E 8% | Bde |
Introduction:
Recombination frequency is a measure of genetic linkage. It is used in creating a genetic linkage map. Recombination frequency (r) can be defined as the rate of occurrence of recombination between a pair of linked gene.
It can be calculated using this formula –
r = Total number of recombinant
Total number of progeny
According to the given problem, 1 map unit corresponds to 1% recombination.
Frequency of specific gamete formation can be calculated from the map of linked genes.

Shown below are photomicrographs of Rhoeo tradescantia cells undergoing meiosis. Answer the following question for each of the photomicrographs:
Identify the cytogenetic abnormality observed (ex. ring, chain, laggard, bridge).
Identify the meiotic stage in which these aberrations are observed (as shown in the photomicrograph).
Explain how these aberrations are formed and relate to the possible causal mutation(s).
Will this result to sterile and/or fertile gametes? Explain.
n corn, male sterility is controlled by maternal cytoplasmic elements. This phenotype renders the male part of the corn plants (i.e the tassel) unable to produce fertile
pollen; the female parts, however, remain receptive to pollination by pollen from male fertile corn plants. However, the presence of a nuclear fertility restorer gene F
restores fertility to male sterile lines

Consider a maize plant: Genotype C/cm ; Ac/Ac+ where cm is an unstable colorless allele caused by Ds insertion. What phenotypic ratios would be produced and in what proportions when this plant is crossed with a mutant c/c Ac+/Ac+? Assume that the Ac and c loci are unlinked, that the chromosome-breakage frequency is negligible, and the C allele encodes pigment production.
