Question

_____You carry out a three point testcross of the genes A B and C and find that the most common genotype in the offspring are AabbCc and aaBbcc and the least common are the AaBbCc and aabbcc. This would indicate that the mother's genes were originally organized in _____ on her chromosomes with _____ in the middle. _____ You carry out a true dihybrid cross of two black guinea pigs and find a ratio in the offspring of 9 black: 4 cream and 3 brown colored pigs. This would indicate to you that inheritance based on the process of _____ is being manifested. _____ You find that heterozygous individuals for a particular trait clearly show the effect of both of the alleles present in their genotype. The term for this mode of inheritance/gene interaction is called _____ _____You carry out a true monohybrid cross with two individuals that are yellow coated mice. The FI individuals are found to occur in the following ratio: 10 yellow: 5 normal individuals. This would indicate to you that the yellow gene is most likely (a) n _____ gene. _____ There is a term used to express that DNA replication has two replication forks associated with each replication bubble. What one word would best describe this feature of the nature of DNA replication? _____ The name of the family of enzymes that are responsible for relieving the DNA strain (super coiling) that occurs downstream of the replication fork is the _____. _____ The key enzyme involved in DNA replication with the following capabilities: 5-3 exonuclease, proofreading, and 3-5 exonuclease activity is _____ _____ The complete functional name for the enzyme that is commonly called Primase is _____ Number 60 and 61 are short answer. Please CHOOSE 2 of the following questions to answer in no more than three sentences (no more). Please be precise and concise _____ place answers in the space provided on this and the next page clearly labelled. A. Please explain/define and delineate between segregation and independent assortment. B. Please explain/define and make clear the distinction between sex-influenced and sex-limited modes of inheritance. C. Please describe the distinction between syntenic genes and linked genes and explain how the results of a dihybrid test cross would be different for each of these relationships. D. Compare and contrast the functional roles of DNA poly I and DNA poly III.

Explanation / Answer

answer:

gene mapping is a three point test cross on her chromosomes with in the middle

we find heterozygous individuals in the trait of an organism
