Answer
The mode of inhertance for flower color is Co-dominance because both the color of plants are expressesing equally in both white and blue spotted flower.
Cross A
Parent I : WWBB (Blue flower with Broad leaves)
Blue flower allele : W and Broad leave allele : B (True breed thats why we write it in a homozygous way)
Gametes of parent I : WB WB
Parent II: Wwbb (Blue and White spotted flower with thin leave)
Blue and white spotted flower genotype: Ww and thin leave allele : b
Gametes of parent II : Wb Wb wb wb
| WB | WB | WB | WB | |
| Wb | WWBb (Blue+ Broad) | WWBb (Blue+ Broad) | WWBb (Blue+ Broad) | WWBb(Blue+ Broad) |
| Wb | WWBb (Blue+ Broad) | WWBb(Blue+ Broad) | WWBb(Blue+ Broad) | WWBb(Blue+ Broad) |
| wb | WwBb (Blue: White + Broad) | WwBb(Blue: White + Broad) | WwBb(Blue: White + Broad) | WwBb(Blue: White + Broad) |
| wb | WwBb(Blue: White + Broad) | WwBb(Blue: White + Broad) | WwBb(Blue: White + Broad) | WwBb(Blue: White + Broad) |
The chance of getting Blue flower with broad leave is 8/16 so 1/2.

1. In one experiment, Mendel crossed a pea plant that bred true for axial flowers with a pea plant that bred true for terminal flowers. All the F1 plants had axial flowers. Which is the recessive trait? Explain your answer. 2. Green pod color is a dominant allele in pea plants (G). If two plants with green pods are crossed, some of the offspring have yellow pods. What are the possible genotypes of the parents? 3. In garden peas, one...

Complete a dihybrid cross between a pea plant (plant 1) with white flowers and wrinkled seeds with a plant (plant 2) with purple flowers and round seeds. Fill in the Punnett square between Plant 1 and Plant 2. Plant 2 is heterozygous for flower color and homozygous for seed color. What are the phenotypic ratios of the F1 generation? Phenotypes: purple flowers with round seeds: purple flowers with wrinkled seeds: white flowers with round seeds: white flowers with wrinkled seeds:...

17. A diploid plant is a dihybrid for flower color (gene “R”)
and leaf size (gene “L”). Its
phenotype is red flowers and large leaves. This plant is crossed to
a tester plant (which has
white flowers and small leaves). The progeny is as follows:
23 Red, large
25 White, small
230 Red, small
235 White, large
What can be concluded about the linkage relationship of the loci in
the dihybrid parent?
A) Genes R and L are unlinked
B)...

1. A plant with red flowers is crossed with a white-flowered plant of the same species. All the seeds, when grown, produce plants with red flowers. Assuming that the flower color is controlled by a single pair of alleles, which allele is dominant and which is recessive? 2. How does inbreeding increase the incidence of recessive disorders in a population? 3. Why does an individual always have only two alleles for a given gene? 4. In cats, the allele (S) for short fur...

A horticulturist sought to test the hypothesis that flower bolor in the plant blue-eyed Mary Collins parviflorais controlled by a single gone locus where paired alles have a dominant-recessive relationship. The horticulturist crossed two plants that produced flowers of different colors, white and magenta, which he believed were true breeding The horticulturist observed that all of the plants resulting from his cross produced blue flowers. When the horticulturist crossed the F1 plants with each other he obtained the following F2...

Question 2b) You are studying a flowering plant that produces remarkable bright green flowers in its wild type. Your colleagues have discovered two new mutant lines of this plant. One new line breeds true for a yellow flower color. Another new line breeds true for a blue flower color. Your group does the following crosses and makes these observations: yellow X green ⇒ F1 is all green ⇒ F2 75% green and 25% yellow blue X green ⇒ F1 is...

7. A red snapdragon flower is crossed with a white snapdragon flower. All of the offspring are pink snapdragon flowers. You study the pink snapdragon flowers and discover that these flowers produce red pigment but at low levels, thus causing the pink color. What type of genetic inheritance is this? What is the genotype of the red snapdragon flower? What is the genotype of the white snapdragon flower? What is the genotype of the pink snapdragon flower? You cross a...

In snapdragons, when true-breeding red flowers are crossed with true-breeding white flowers, all the offspring exhibit pink flowers. When true-breeding tall snapdragons are crossed with dwarf snapdragons, all the offspring are tall. A researcher decided to perform a dihybrid cross with the above characters and obtained all pink, tall snapdragons (F1). It was then decided to perform across with members of the F1 generation. What are the expected phenotypic ration for the F2 generation? (PLEASE INCLUDE LEGENDS, PUNNET SQUARES and...
