CROSSING OVER
Test Your Knowledge on Crossing Over
Welcome to the Crossing Over Quiz! This quiz is designed to challenge your understanding of the genetic process known as crossing over. Whether you're a student, teacher, or just someone interested in genetics, this quiz is for you!
You'll be presented with questions covering various aspects of crossing over, including:
- The stages of crossing over
- The significance of genetic recombination
- Understanding chromosomal interactions
Crossing-over takes place in the
(a) Diakinesis stage
(b) Anaphase stage
(c) Pachytene stage
(d) Leptotene stage
Alleles of different genes that are on the same chromosome can occasionally be separated by a phenomenon called
(a) Crossing over
(b) Continuous variation
(c) Pleiotropy
(d) Epistasis
Crossing over in diploid organism is responsible for
(a) Recombination of linked genes
(b) Segregation of alleles
(c) Dominance of genes
(d) Linkage between genes
Which of the following statements about crossing-over is most correct?
(a) There are as many crossings over possibilities as there are genes on the chromosome
(b) The farther apart are the two genes on chromosome, greater are the chances of their crossing over.
(c) Genes placed linearly adjacent on a chromosome have the greatest chances of crossing over
(d) Crossing over does not occur at a distance of more than 5 map units
Crossing over that result in genetic recombination in higher organisms occurs between
(a) Two different bivalents
(b) Sister chromatids of a bivalent
(c) non sister chromatids of a bivalent
