Which statement about a dihybrid cross (resulting in a 4×4 square) is true?

Which statement about a dihybrid cross (resulting in a 4 x 4 square) is false?

The specific name of the 5-carbon sugar that is found in DNA is _______.  This 5-carbon sugar is a ________.

If homozygous plants with round seeds are crossed with homozygous plants with wrinkled seeds, then the F1 plants all have round seeds. If these offspring are allowed to self-pollinate (F1 crossed with F1), what fraction of the F2 generation will be both round-seeded and homozygous?

Which statement about Mendelian genetics is false?

Green and yellow are two alleles of the same gene for stripe color. Suppose members of a homozygous strain of salamanders with yellow stripes are crossed with a homozygous strain with green stripes. The resulting offspring have both yellow stripes and green stripes.  Which dominance pattern is most consistent with the observations?

In garden peas, the allele for tall plants is dominant over the allele for short plants. A true-breeding (homozygous) tall plant is crossed with a short plant, and one of their offspring is test crossed. Out of 20 offspring resulting from the test cross, about _______ should be tall.

(1 point).   In rabbits, phenotype A (white fur and long ears) is caused by dominant alleles for both white fur (F) and long ears (G); phenotype B (black fur and short ears) is caused by recessive alleles for both black fur (f) and short ears (g). In the parental generation, a rabbit that is homozygous dominant for both traits of phenotype A is mated to a rabbit that is homozygous recessive for both traits of phenotype B. 1. What is the genotype AND phenotype of the parents? 2. What is the genotype AND phenotype of the F1 generation? 3. If you cross an F1 with an F1 and complete the 4×4 Punnett square: What genotype would you find in the upper left corner of the Punnett square? What genotype would you find in the lower right corner of the Punnett square? 4.  In the F2 generation, what is the expected ratio of phenotypes listed below, given the following possible phenotypes?        Phenotype A:  white fur and log ears        Phenotype B:  black fur and short ears        Phenotype C:  white fur and short ears        Phenotype D:  black fur and long ears a. 1A:1B b. 1A:0B c. 3A:1B d. 9A:3C:3D:1B e. 9B:3C:3D:1A

In a species of pea plant, the green seed allele (G) is completely dominant over the yellow seed allele (g). If the alleles for height are incompletely dominant, such that HH is tall, Hh is intermediate, and hh is short, what F1 offspring will result from crossing a green-seeded short (GGhh) plant with a yellow-seeded tall (ggHH) plant?

Segregation (separation) of alleles occurs
