Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...

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...

Questions 64-65 refer to the following. In a plant, axial flower (T) is dominant to terminal flower (t) and red fruit color (Y) is dominant to yellow (y). These effects are caused by two independently assorting autosomal genes. An individual terminal red plant was crossed with an individual axial, yellow plant to produce offspring which were 1/2 axial, red: 1/2 terminal, red. The genotype of the crossed terminal red plant was: ttyy ttYy ttYY TTyy Ttyy In the cross described...

genetic cross question
In a trihybrid cross in garden pea plants that differ in plant height (tall is dominant to dwarf), flower color (purple is dominant to white), and seed color (yellow is dominant to green), what is the probability of getting a tall plant with purple flowers and green seeds in the F2 generation. The three genes are on separate chromosomes. 03/16 09/16 27/64 3/64 9/64

CONTENT QUESTIONS (answer these for credit) 1. In an experiment to trace the inheritance of two traits in pea plants, a researcher decided to look at height, which is controlled by two alleles. The dominant allele T produces a tall plant while the recessive allele t produces a short plant. Flower color is controlled by one gene with two alleles as well. The dominant allele P produces purple flowers, and the recessive p produces white flowers. If the female parent...

PROCEDURE: Analysis of a pedigree The most common type of color blindness is red-green Coreessive color perception defeet. It's due to a blind allele). X-linked red-green have normal vision, but mutation on the X chromosome (i.e. a red-green color color blindness is a recessive trait. Females heterozygous are carriers of the trait. The color perception defect man inherited from both parents (homozygous recessive). Byor blind if the inenedigree c chromosome from their mothers and become red-green color chromosome has the...

1. What ratio of offspring would result from a cross between a white-eyed male and a female that is heterozygous for red eye color? 2. If black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be indicative of? a. dominance b. codominance c. multiple alleles d. incomplete dominance 3. The ABO blood groups in humans are expressed as the IA, IB, and i alleles. The IA allele encodes the A...
