Question 25 A landscaping company wants to sell plants with flowers that are purple to match the company logo. It is known that this species of plant is capable of producing both purple and white flowers. You are tasked with ensuring no white flowers appear during propagation scale up of the purple flower plants. Before starting, you need to know the genotype of the plants with purple flowers and that with white flowers. It was previously established that the purple color is due to a pigment produced by a well-known biosynthetic pathway. You deduce that white flowers result from lack of the pigment and therefore white is recessive (p) to purple (P). To begin the propagation program, you have a been given a flower of each color. 4 p What is the most efficient procedure you could use to be sure the plants you provide to the company will produce only purple flowers? Choose the best answer from the list below. O Inbreed plants of both colors for 6 generations O Produce an F2 generation O Determine if the gene for flower color has co-dominant alleles O Produce an F1 generation O Do a back cross O Do a test cross

QUESTION 3 In Drosophila, miniature wings (X) result from an X-linked allele that is recessive to the allele for long wings (X). Give the most likely genotypes of the parents in each of the following crosses: Male Parent Female Parent Cross #1 Cross #2 Long Miniature Genotype for male parent #1: Genotype for female parent #1: Genotype for male parent #2: Genotype for female parent #2: Long Long Male Offspring 231 Long 250 Miniature 420 long 417 Miniature Female Offspring 560 Long 0 Miniature 412 Long 415 Miniature Use Xm and X+ for the allele symbols in your answers as there is not a superscript option. Also, remember that males are hemizygous!

Please answer fast You obtain the following number of offspring in a test cross of a dihybrid plant with a test cross parent with the given phenotype. The test cross is:   Tt Pp x tt pp the expected phenotypic ratio 1:1:1:1   what is the chi-square value for this chi-square?   Tall purple flower: 36   Tall white flower: 37   Short white flower: 34   short purple flower : 33

Question 1 The possession of one of two types of earlobes (hanging or attached) is sometimes used to study the inheritance of characteristics in humans. The pedigree shows the different types of earlobes present in three generations. KEY male with hanging earlobes II female with hanging earlobes male with attached earlobes female with attached earlobes III Discuss the type of inheritance shown in the pedigree. In your answer, include reference to the alleles involved using standard notation.

Question:- 1. Brassica oleracea is the wild plant from which brussels sprouts, cabbage, broccoli, and cauliflower were domesticated. Why is it important to keep many diverse seeds from the forb B. oleracea across its range?   A. If our B. oleracea-derived crops are driven to extinction, we can re-domesticate them from the wild plant.   B. Our crop Brassicas are much more genetically diverse than B. oleracea because of extensive breeding programs, so we need to conserve as much of B. oleracea's diversity as possible.   C. The budding pattern in Brassica may be further modified to produce more productive crop plants.   D. B. oleracea may have gene variants that can be incorporated into our domesticated plants to increase their environmental range or tolerance to pests.   E. We may be able to domesticate another crop plant from B. oleracea.

QUESTION 6 In Drosophila, sepia eyes (se) and stubble bristles (sb) are recessive to the wildtype eyes and bristles (se* and sb+). A female heterozygous for both genes was test crossed to a male homozygous recessive for both genes. The progeny of this cross are given below: Phenotypes wildtype eyes and wildtype bristles (set, sbt) # of Progeny 334 widltype eyes and stubble bristles (set, sb) 162 sepia eyes and wildtype bristles (se, sb+) 158 sepia eyes and stubble bristles (se, sb) 346 What is the genetic distance (in map units) between these two genes? Are the alleles in the heterozygous female in the cis (coupling) or trans (repulsion) conformation? Are the two genes in this problem unlinked, completely linked or incompletely linked?
