the swaping of genetic material during meiosis
Answers
Explanation:
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.
Answer:
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.
Explanation:
Crossing over takes place during pachytene stage of Prophase I of Meiosis I where the non sister chromatids of homologous chromosomes exchange genetic material, this results in recombination of the genetic material and creates new genetic combination. This results in variations, which can be beneficial to the offsprings providing a better survival advantage.
So, the correct answer is 'Crossing over produces new combinations of genes on alleles, increasing genetic variation. Genetic diversity increases the fitness of the population'
