35. A testcross (backcross) is used to determine: a. an individual has a dominant or recessive...
Bants and white fnowered plants show incomplete dominance ie the allele for white flowers are incompletely dominant and it is possible to get flowered plants b. Suppose that red flowered plants R for red flowers and the allele R' flowers are pink flowered plants, cross a pink another p nowered plant with another pink flowered plant using a Punnett square Complete the following What is the genotype of each pink fowered parent plant was it possible to get white flowered...
For questions 5 and 6: Tall (T) is dominant to short (t) 5. Ifa homozygous tall plant is crossed with a short plant, what percentage of the offspring will be tall? , The two parents used in this cross are called as breeding parents. 6. Iftwo heterozygous tall plants from the above are crossed, what percentage of the offspring will be short? For questions 7, 8 and 9: Purple (R) is dominant to white (r) If two white flowered plants...
Mendelian Genetics Lab Practice Mendelian Genetics Lab Practice Practice with Crosses. Show all work below: 9. In pea plants purple flowers are dominant to white flowers. Two white flowered plants are crossed... 5. ATT (tall) plant is crossed with a short plant). What percentage of their offspring wil have white flowers? What percentage of the offspring will be tall? 10. A white flowered plant is crossed with a plant that is heterozygous for the trait. 6. Show the cross of...
12) In peas, the yellow seed color is dominant (YY or Yy) over the green seed color (vy). You have been given a plant that only produces yellow seeds and need to determine if the plant is YY or Yy. Which of the following crosses would be most effective for determining the genotype of your plant? A)your plant x a plant that produces only green seeds B)your plant x another plant with known genotype YY C)your plant x another plant...
Merritt, 2016 BIO 1511 NAME:F. I.) 10-15 Post Lab #10 Post-LabE19: BASIC GENETICS PROBLEMS # Correct Answers: (16) (Last) Lab Day: MWF(circle one) Solve the genetics problems in this handout. For all problems, assume complete dominance, assume one gene codes for one trait, and assume there are only 2 different alleles possible for each gene (dominant or recessive) 1. If a homozygous dominant red flowered plants are crossed with homozy phenotypes and genotypes of the offspring? Show the genotypes of...
4. In summer squash, fruit color and shape are controlled by two independently assorting genes as follows: Trait Gene Alleles Phenotypes Fruit color W W w White fruit yellow fruit Fruit shape D D d Disk-shaped fruit sphere-shaped fruit A homozygous White Disk plant has been crossed with a homozygous Yellow Sphere plant (this is the P1 generation). List the expected genotype and phenotype of the F1 plants? P1 WWDD x wwdd F1 WwDd Genotype: WwDd Phenotype: White, Disk If...
0. In snapdragons, the alleles for flower color show incomplete dominance. CRCR produces red flowers; CWCW produces white flowers and CRCW produces pink flowers. The height of the plant is determined by a separate gene with regular dominant and recessive alleles. Normal height (D) is dominant over dwarf height (d). a. A snapdragon that is heterozygous normal in height and has white flowers is crossed with a plant that is dwarf in height and has red flowers. What is the...
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...
1) The alternate forms of a gene for the same trait are known as -A)alleles. B)phenotypes. C)genotypes. D)codominants. E)incomplete dominants. 2) Mendel carried out most of his research with A)livestock -B)pea plants. C)guinea pigs. D)fruit flies. E)bacteria. 3) Which of the following is true according to Mendel's law of segregation? A)Each individual contains two alleles for each trait. B)Fertilization restores the presence of two alleles. C)Alleles separate from each other during gamete formation. D)Each gamete contains one copy of each...
1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...
