Chapter 10, Problem 1GP
Summary Introduction
To determine:
The most common genotype of the F2 generation of the rose bushes.
Concept introduction:
Gregor Mendel had discovered the basic genetic principles. He had taken pea plants for his experimental work and observations. He had selected the pea plants because they were easy to grow, produced multiple offsprings and developed quickly and was also a good choice for studying heredity. True breeding refers to self-fertilization and production of offspring’s same as that of the parent plant.

In pea plants, flower color is determined by one gene with two alleles, with the allele coding for purple flowers (P) being dominant to the allele coding for white flowers (p). If two purple-flowered offspring resulting from a cross between homozygous dominant and white-flowered parents are crossed, what percentage of the progeny are expected to have the dominant phenotype?
When a white guinea pig is crossed to a yellow guinea pig, all the progeny are cream colored. From a cross of two such F1’s, the F2 showed 32 white, 66 cream, and 30 yellow guinea pigs. How is this trait inherited?
In venetian violets, three phenotypes occur with respect to flower color: a deep violet (almost back), a white, and a pale lavender. Two pale lavender flowered plants have been crossed. The F1 from this cross has individuals with deep violet flowers, with pale lavender flowers, and individuals with white flowers.
A. what are the parent genotypes?
B. what would the expected phenotypic ratio be in these F1 plants?
