What is the role of meiosis in causing variation in offspring
Answers
Answer:
Meiosis leads to the formation of gametes which have half the number of chromosomes in the somatic body cells. This means two gametes should fuse together for a new individual to form. The two gametes coming from two different parents carry features from two individuals, and this is the first source of variation.
Answer:
Explanation:
Meiosis, otherwise called reduction division. As the name itself implies that something is reduced into something.
Normally cell divisions are of two types; Mitosis or Meiosis.
Mitosis is usually common among organisms. But meiosis, meaning lessening, is a special type of cell division in sexually reproducing organisms used to produce gametes. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome (haploid). Prior to the division, genetic material from the paternal and maternal copies of each chromosome is crossed over, creating a new combinations of code on each chromosome. Later on, during cell fertilisation , haploid cells produce by meiosis from a male and female will fuse to create a cell with two copies of each chromosome again, the zygote.
Crossing over and recombination are the cause of variation in offspring thus produced.
