Homework Answers
Each gamete receives a single allele of each trait at the time of cell division from each parent. The law of segregation states the separation of the two alleles of each trait is random and there is a 50% chance of either allele to be transferred in either gamete.
The law of independent assortment states that the separation of the allele of one gene is independent of an allele of the other gene. Therefore, the law of independent assortment describes the behavior of the separation of the two or more genes with respect to one another.
Hence, the option "A" is correct.

Which of these statements is incorrect? Syntenic genes are located on the same chromosome. Independent assortment results in recombinant chromosomes. You can reliably predict the relative genetic distance from genes’ physical distance on a chromosome. Linked genes are always syntenic. What is the relative genetic distance between two linked genes if the recombination frequency is 0.49? 0.49 cM 4.9 cM 49 cM 490 cM What statement best explains the distortion in Mendelian ratios observed by Bateson & Punnett in 1905?...
