Chapter 17, Problem 22P

Cytoplasmic male sterility (CMS) in plants has been exploited to produce hybrid seeds (see Experimental Insight 17.1 ). Specific CMS alleles in the mitochondrial genome can be suppressed by specific dominant alleles in the nuclear genome, called Restorer of fertility alleles, RF. Consider the following cross:

CMS 1Rf1/Rf1 rf2/rf2  × CMS2 rf1/rf1 Rf2/Rf2

What genotypes and phenotypes do you expect in the F 1 ? If some of the F 1 plants are male fertile, what genotypes and phenotypes do you expect in the F 2 ?

Blurred answer

Multiple crosses were made between true-breeding lines of black and yellow Labrador retrievers. All the F1 progeny were yellow. When these progeny were intercrossed, they produced an F2 consisting of 121 yellow, 9 black and 30 chocolate.   What epistatic ratio and what kind of epistasis is approximated in the F2?     Propose a biochemical pathway for coat color in Labrador retrievers based on the type of epistasis.     Correlate each genotype with the phenotype that would occur in your pathway. Also show the frequency of each genotype. A-B- A-bb aaB- aabb
Explain at the biochemical or enzymatic level, the phenotypic consequencesof alleles incase of following cross. Rr (pink flower) x Rr (pink flower) (progeny are 1 RR (red flower) :2 Rr (pink flower): 1rr(white flower) how alleles contribute to a phenotype through metabolism.
In 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  Using the cardboard chips, simulate the crosses indicated below. Give the genotypes and phenotypes of the offsprings in each cross, and properly label the nucleus and the cytoplasm of each individual in the cross    Legend     male sterile cytoplasm      Male fertile cytoplasm      FF nucleus      Ff nucleus      ff nucleus    A. Male sterile female x FF male  Explain the phenotype of the offspring  B. Male sterile female x Ff male  Explain the phenotype of the offspring
