You cross two pea plants that are heterozygous for the pea texture gene with alleles R-dominant-rough and r-recessive-smooth. Show your reasoning/math as you describe the probability that in a pod with 4 peas: all of the peas have the same phenotype (either rough or smooth).

You are conducting independent research for your Honors Thesis in a Drosophila research lab.  One of the graduate student researchers has provided you with two mutant strains of Drosophila.  One has scarlet eyes, and the other has brown eyes.  You cross homozygous scarlet-eyed male Drosophila with female flies homozygous for the brown-eye color allele, and all of the male and female F1 flies have wild-type eyes.  Crosses involving F1 males x F1 females yield the results shown below. You know the traits involved are autosomal, and that reciprocal parental crosses produce similar results.   a) What is the phenotypic ration observed among the offspring in the F2 generation? b) How many pairs of genes are involved in determining these traits? Please explain. c) Please EXPLAIN the genetic basis for the pattern of inheritance illustrated in this cross. Be sure to mention the alleles involved.

Mendel crossed a wrinkle-seeded plant with pure round-seeded plant. Round is the dominant trait. Create a Punnett Square to represent this relationship. Using this information outlined in this Punnett Square, what percentage of the offspring do we anticipate will be wrinkle-seeded? (Chp 2) O 100% O 75% O 50% O 25% 0 0%

You know the traits involved are autosomal, and that reciprocal parental crosses produce similar results. A) Please define the alleles represented in this cross.  B) List the genotypes of all classes of individuals in the P, F1, and F2Be sure to use the alleles you defined in Part A Parental (P) Generation Genotype of Homozygous scarlet-eyed males: Genotype of Homozygous brown-eyed females: F1 Generation: Genotype of Wild-type (red-eyed) males and females: F2 Generation: Genotype of wild-type males and…
