The plant Arabidopsis thaliana was transformed by using the Ti plasmid into which a kanamycin resistance gene had been inserted in the T-DNA region. Two kanamycin-resistant colonies (A and B) were selected, and plants were regenerated from them. The plants were allowed to self-pollinate, and the results were as follows: Plant A selfed Plant B selfed → 3/4 progeny resistant to kanamycin → 1/4 progeny sensitive to kanamycin 15/16 progeny resistant to kanamycin 1/16 progeny sensitive to kanamycin

A research scientist is studying diseases associated with homologous chromosomes and notices that the same gene along the chromosome has different function what can you conclude about his findings? A. The homologous pairs have been recombined and therefore he is studying end joining of chromosomes B. He is studying sex chromosomes and the differences are because the chromosomes are from a male species organism C. He has identified different alleles among homologous chromosomes. D. He is studying basic chromosome remodeling during fertilzation

What is the name of the specific type of chromosomal abnormality present in the individual plant whose chromosomes are diagrammed above? Please DESCRIBE each of the four chromosomes by indication the chromosome pair to which it belongs, is it the "normal" version of the chromosome or the version that has undergone a chromosomal rearrangement, and specify the type or rearrangement present. (For example, indicate that a chromosome is the normal version of Chromosome #1, or the version of Chromosome #1 containing a ( ) (where you would mention the type of rearrangement present).
Vhich statement best explains why so many variations in coat colors exist? O Each coat color is the result of mutations that take place after the horse is born. The recombination of genes during meiosis results in offspring that exhibit a variety of coat colors. O Varying gene expression after fertilization leads to a variety of coat colors. O Recombination during mitosis leads to the expression of different coat colors as the horse develops.
