Chapter 14, Problem 1SQ
Summary Introduction
Introduction: A pedigree depicts the interrelationships between parents and offspring over generations for a particular trait. It is also referred to as a family tree. Individuals and relations are denoted by symbols and lines. It contributes in predicting the occurrence of that particular trait in future generations through inheritance patterns and genotyping the individuals.

- A developmental system underlying a trait may evolve so that it resists environmental influences on the phenotype. Such a system is refered to as _______. A. coalescence B. stabiliztion C. canalization D. subfunctionalization.arrow_forwardA heterozygous individual has_____ for a trait being studied. a. the same allele on both homologous chromosomes b. two different alleles of a gene c. a haploid condition, in genetic termsarrow_forwardYou are doing a genetics experiment with the fruit fly. In the “P” generation, you cross two true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. Answer all the questions below. 3a. What is the genotypes of P generation? 3b. What is the genotype of the F1 generation? 3c. You now take an F1 female and cross her to a true-breeding black, wingless male so what is the male’s genotype? 3d. You count 1600 offspring in the F2 generation. If the wing and the color traits were linked and no recombination occurred, what would you expect the numbers of: 1. brown winged flies (BbNn) 2. black winged flies (Bbnn) 3. brown wingless flies (bbNn) 4. black wingless flies (bbnn). 3e. What is the genetic distance between the color and wing genes when you count the F2 generation as 85 brown winged flies, 728 black winged flies, 712 brown wingless flies, and 75 black wingless flies.arrow_forward
