GENETICS:

True or false? If false explain why these statements are false. Will give a thumbs up if correct.

When a cell of the genotype A/A; B/B; c/c having all three genes on separate chromosome pairs divides meiotically, the genotype of the daughter cells would be A/A; B/B; cc hoilse, devghter cell would be Be B 2 behavior is that the genes controlling these traits reside on different chromosomes Mendel identified seven traits that assorted independently. The only explanation for this Individuals homozygous for a recessive mutation in the p53 gene develop skin cancer at an early age. An individual known to be heterozygous for the p53 mutation develops skin cancer. Analysis reveals that the cancerous cells are homozygous for the p53 mutation. The only explanation for this is that a mutation occurred in the remaining normal p53 allele in these cells GeneA, geneB, geneC and geneD reside on chromosome2 of Drosophila. Genes A and B 4 are separated by 10 m.u. Similarly genes C and D are separated by 10 m.u. One concludes from this data that the same physical distance separates the genes along the chromosome. A true breeding double dominant strain of corn (AABB) is crossed to a true breeding double recessive strain (aabb). The F1 plants (AaBb) are then test crossed. If the A/a locus is linked to the B/b locus then we should expect more Ab and aB gametes compared to AB and ab gametes in the F1 plants In meiosis, homologous chromosomes pair and separate in anaphasel; sister chromatids 6 separate in anaphaselI Reductional division refers to the separation of sister chromatids in mitotic anaphase
