Homework Answers
Answer:
1. E) None of the above
explanation: Both the parents are pure breeding hence both parents are homozygous. One parent is homozygous dominant while the other is homozygous recessive.
2. A) All are heterozygous
Explanation: In mendel experiment, When one homozygous is crossed with homozygous recessive, then all the F1 progeny are heterozygous receiving one dominant allele from homozygous dominant parent and one recessive allele from the homozygous recessive parent.
3. D) About 50 percent will be heterozygous
Explanation: In F2 generation, the genotypic ratio will be 1:2:1 indicating 25 % homozygous dominant, 50 % heterozygous and 25% homozygous recessive.
4. B) all will be long blue pods
5. D) 32
Explanation: Number of heterozygous alleles = n = 5
number of possible combination = 2n= 25 = 32
6. D) 16

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...

When Mendel crossed pure breeding peas having purple flowers with pure breeding peas having white flowers, all of the offspring had white flowers. These results mean that white flower color is the: a.) genotype. b.) dominant phenotype. c.) recessive phenotype. d.) mode of inheritance.

Mendel bred pea plants for multiple generations to ensure they were true-breeding. What is true-breeding? The organism always produces offspring every time it breeds. The organism will only breed with itself. The organisms will only breed with others that have the same trait. The organisms always produce offspring with the same traits as the parent. Question 2 The F1 generation can best be described as... the first generation the offspring of the P generation the homozygous generation

In an experiment, homozygous dominant plants with purple flowers were crossed with homozygous recessive plants with white flowers. Mendel collected the seeds from this cross, grew F1-generation plants, crossed them to form a second generation, and then analyzed the plants of the resulting F2 generation. What results did he probably get? 1/2 the F1 and 3/4 of the F2 generation flowers were white 1/2 the F1 and 1/4 of the F2 generation flowers were purple 3/4 of the F1 and...

5. In Mendel's experiments, the pod color gene and the seed shape gene were located on different chromosomes (in other words, they were not linked. They assort independently). Green pods (G) are dominant over yellow pods (g) and tall stems (T) are dominant over dwarf stems (t). You are given two true breeding plants (homozygous at both genes). In the parental (P) generation, one parent has green pods and dwarf stems and the second parent has yellow pods and tall...

2. A Pea plant that is Homozygous Dominant for purple flower color and Heterozygous for dark green leaves is crossed with another pea plant that is Heterozygous for both purple flower color and dark green leaves Let R = Purple flower color and r = white flower color Let D = Dark Green leaves and d = light green leaves Data Collection/Selection Using the information above, write the parent genotypes and gametes. Not all blanks may be used. Parent Genotypes:...

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...

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...

An agronomist crossed two true breeding Guava plants. one parent is characterized by being Round, terminal, violet and constricted, while the other expresses the contrasting phenotype of wrinkled, axial, white and full. Assume that the four pairs of contrasting traits are controlled by four genes (RTVC) with each located on a separate chromosome. In the F1 generation, only round, axial, violet and Full were expressed while in the F2 generation all possible combination of these traits were expressed ratios consistent...
