It doesn't always. When crossing over occurs sections of nucleotide bases are switched. Lets take for example you have an original DNA of TTCTCCGATAGT and crossing over occurs to change this into TTCATGGATTCT. When this is now read by the mRNA only ATG will become a different protein meanwhile AGT on the original will be made into the same protein. This is because you have to look at the codon table to see which codons become which protein. Different codons may produce the same proteins so crossing over does not always ensure genetic variation but is gives genetic variation a more likely probability of happening. As for independent assortment, this doesn't lead to genetic variation. Really independent assortment will just lead to different phenotypes being expressed.
Crossing over is the exchange of genetic material between homologous chromosomes during meiosis, leading to genetic variation. Independent assortment is the random distribution of homologous chromosomes during meiosis, also contributing to genetic diversity.
Independent assortment refers to the random distribution of different genes into gametes during meiosis, resulting in genetic variation. Crossing over is the exchange of genetic material between homologous chromosomes during meiosis, leading to further genetic diversity.
In genetic recombination, crossing over and independent assortment are two processes that shuffle genetic information. Crossing over involves the exchange of genetic material between homologous chromosomes, leading to new combinations of genes. Independent assortment is the random distribution of homologous chromosomes during meiosis, resulting in different combinations of genes in offspring. Both processes contribute to genetic diversity by creating unique combinations of genes in offspring.
Independent assortment refers to the random distribution of different genes during the formation of gametes, leading to genetic variation. Crossing over, on the other hand, is a process during meiosis where homologous chromosomes exchange genetic material, resulting in new combinations of genes. Independent assortment increases genetic diversity by shuffling genes from different chromosomes, while crossing over creates variation by swapping genetic material within the same chromosome.
New genetic combinations result from processes such as genetic recombination during meiosis, random assortment of chromosomes, and independent assortment of alleles. These processes lead to the creation of unique genetic profiles in offspring.
The crossing over is the process of exchange of DNA between homologous chromosomes whereas the independent assortment is the process in which the chromosome pairs align themeselves at the equator of the cell . Crossing over takes place in Prophase I of meiosis I whereas the independent assortment takes place in metaphase I of meiosis I.
A new combination of genes produced by crossing over and independent assortment refers to the genetic variation that occurs during meiosis. Crossing over involves the exchange of genetic material between homologous chromosomes, while independent assortment ensures that chromosomes are distributed randomly to gametes. Together, these processes create unique combinations of alleles in the offspring, contributing to genetic diversity within a population. This variability is crucial for evolution and adaptation.
Crossing over and independent assortment
Mutations, crossing over, and independent assortment contribute to genetic variation in daughter cells during meiosis. Mutations introduce new alleles, while crossing over mixes genetic material between homologous chromosomes, leading to unique combinations of genes. Independent assortment further randomizes the distribution of maternal and paternal chromosomes into gametes. Together, these processes ensure that each daughter cell has a diverse genetic makeup, enhancing variability in a population.
Meiosis, which includes crossing over and independent assortment
Crossing over is the exchange of genetic material between homologous chromosomes during meiosis, leading to genetic variation. Independent assortment is the random distribution of homologous chromosomes during meiosis, also contributing to genetic diversity.

The random distribution of homologous chromosomes during meiosis is called independent assortment
Independent assortment refers to the random distribution of different genes during the formation of gametes, leading to genetic variation. Crossing over, on the other hand, is a process during meiosis where homologous chromosomes exchange genetic material, resulting in new combinations of genes. Independent assortment increases genetic diversity by shuffling genes from different chromosomes, while crossing over creates variation by swapping genetic material within the same chromosome.
New genetic combinations result from processes such as genetic recombination during meiosis, random assortment of chromosomes, and independent assortment of alleles. These processes lead to the creation of unique genetic profiles in offspring.
The two sources of genetic variation in a cell during Meiosis are crossing-over during synapse and independent assortment.
