Genetic Variation During Meiosis
Scelta multipla
What is the relationship between the degree of crossing over and the distance between two genes during meiosis?
A
The degree of crossing over increases with the distance between two genes.
B
The degree of crossing over decreases with the distance between two genes.
C
The degree of crossing over is unaffected by the distance between two genes.
D
The degree of crossing over is inversely proportional to the distance between two genes.
Guida verificata passo dopo passo1
Understand that crossing over is a process during meiosis where homologous chromosomes exchange genetic material, leading to genetic variation.
Recognize that the likelihood of crossing over between two genes is related to their physical distance on a chromosome.
Recall that genes that are farther apart on a chromosome are more likely to experience crossing over because there is more space for the exchange to occur.
Consider that genes that are closer together are less likely to experience crossing over because there is less opportunity for the exchange to happen.
Conclude that the degree of crossing over increases with the distance between two genes, meaning that the farther apart the genes are, the more likely crossing over will occur between them.
