There wouldn't be any variety in the human population. Everyone would look more or less the same. This is because crossing over in meiosis allows the chromosomes to exchange genetic information to ensure that each daughter cell is unique and therefore, when reproducing, each person is also unique.
Children would probably look more like their parents.
Children would probably look more like their parents.
Any two of: Mutations Non-disjunctions during anaphase of meiosis Polyploidy Sexual reproduction e.g. crossing-over/recombination during meiosis IF YOU ARE LOOKING FOR THE STUDYISLAND ANSWER IT IS a population whose members have many different traits
Crossing over is a process that occurs during meiosis.
During meiosis, crossing over occurs when homologous chromosomes exchange genetic material. This process creates new combinations of genes, leading to increased genetic variation in offspring.
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
crossing over during meiosis is important in that it allows the occurrence of various genes, this is it promotes the increase of different genes. lets remember that meiosis occurs in sexually producing animals and that the first phase of meiosis is the reduction of the haploid number to the diploid number. this reduces the occurrences of increasing numbers in chromosomes. crossing over takes place during pro-phase
Crossing over occurs during Prophase I of meiosis.
Crossing over occurs during Prophase I.
Crossing over recombines linked genes by exchanging genetic material between homologous chromosomes during meiosis. Unlinked genes are not affected by crossing over as they are located on different chromosomes and segregate independently during meiosis.
During crossing over in meiosis, four genetically distinct gametes are produced.
Crossing over between homologous chromosomes occurs during prophase I of meiosis.
