Question
If 50% recombination occurs (two parental types and two recombinant gametes), the transmission is then indistinguishable from independently assorting genes. Yes No Assume that a cross is made between AaBb and aabb plants and that the offspring occur in the following numbers: 1060 AaBb, 480 Aabb, 520 aaBb, 940 aabb. These results are consistent with _____ sex-linked inheritance with 30 percent crossing over linkage with approximately 33 map units between the two gene loci linkage with approximately 30 map units between the two gene loci independent assortment 100 percent recombination Methods for determining the linkage group and genetic map in humans involve _____ DNA markers twin spots and tetrad analysis tetrad analysis and bromodeoxyuridine zygotene and pachytene DNA synthesis chiasmatype and classical analyses In a population of 100 individuals, 49 percent are of the NN blood type. What percentage is expected to be MN assuming Hardy-Weinberg equilibrium conditions? 9 percent 21 percent 42 percent 51 percent There is insufficient information to answer this question. Albinism is an autosomal recessive trait in humans Assume that there are 100 albinos (aa) in a population of 1 million. How many individuals would be expected to be homozygous normal (AA) under equilibrium conditions? 100 10,000 19, 800 980, 100 999, 900 Which method is often used to analyze proteins and nucleic acids by physical separation when estimating genetic variation in populations? electrophoresis centrifugation absorption spectrophotometry fluorometry in situ hybridizationExplanation / Answer
Ans 28 yes
When 2 genes are located on different chromosomes or there is no linkage in between them , then the maximum recombination frequency observed will be 50%. So the segregation of alleles take place according to second law of mendel, that is they assort independently of each other.
