Name: PRELAB QUESTIONS 1. Define the following terms: Gene- Allele - Phenotype- Genotype- Homozygous dominant - Homozygous recessive- Heterozygous- 2. Put into your own words Mendel's law of segregation. LI Does the law of segregation always apply when dealing with genes located on chromosomes within a diploid nucleus? If not, explain why. 3. Mendel worked with several pea plant characters, each of which was determined by a single gene with two alleles, one dominant and the other recessive. For each...

98 Mendelian Genetics Exercise D: Mendel's Dihybrid Cross But wait there's morel Mender's monohybrid crosses established that inheritance of phenotypes happened by the interactions of discrete particles' (we now call alleles). Further, he discovered that those alleles segregate during the process of meiosis in the production of gametes, which recombine during fertilization. The result of these two insights can easily be predicted by a technique developed by R. C. Punnett. Once these principles were established, Mendel sought to understand how...
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. For each genotype, indicate whether it is heterozygous (HE) or homozygous (HO) AA __HO__ Bb __HE__ cc __HO__ Dd __HE__ 2. For each of the genotypes below, determine the phenotype. (P=purple, p=white) Purple flowers are dominant to white flowers PP ________________________Homogeneous Dominate Pp ________________________Heterozygous pp _______________________Homozygous Recessive 3. In guinea pigs, the allele for short hair is dominant. S= Short Hair s= long Hair What genotype would a heterozygous short haired guinea pig have? ____Ss___ What genotype would a...
Help Center 07 Question 38 What phenotypic ratio of offspring would result from a cross between a white-eyed male fruit fly, and a female that is heterozygous for red eye color? (See Chapter 8.3 Figure your e Text) 2 white-eyed females 2 red-eyed males V none of these 2 red-eyed female 1 white-eyed female: 1 red-eyed male: 2 white-eyed male 1 red-eyed female 1 white-eyed female 1 red-eyed male: 1 white-eyed male 2 red-eyed females: 2 white-eyed males Question 39...
Question 12 only. Punnett's square analysis for the parental cross r Rr Rr 9) If we used the above offspring (F1) in a new cross, what would be the genotypes and phenotypes of the offspring of the Fz generation? 10) What is the genotypic ratio of the F2 generation? 11) What is the phenotypic ratio of the F2 generation? 12) What would be the genotypic and phenotypic ratios of offspring from a cross between a homozygous recessive parent (r r)...
5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

6. In tigers, a dominant allele (W) is responsible for the expression of the normal orange pigment. Individuals that inherit twe recessive alleles (w) lack the normal orange pigment in their fur, appearing white with black stripes. A pair of normally colored parewis produces a cub that is white with black stripes and scab that is orange with black stripes. What are the possible genotypes of the cube? b. What are the possible genotypes of the parents? 6. Explain your...
