fusion of gametes via fertilization
Both straight and gay sexually. Bisexual.
The genetic material of a sexually reproducing organism evolves for better adaptations.
They are produced sexually.
If there is a sudden change in genetic variability, the habitat of the pest or fungi population's changes in growth it wouldn't properly reproduce sexually and asexually because some pest or fungi survive depending on the environment.
in crossing over the gens present on chromosomes forms linkage so the character are exchange & thus it lead to recombination of genes that affect genetic diversity
No, sexually reproduced organisms are not genetically identical to their parents. They inherit a unique combination of genetic material from both parents, resulting in genetic variation. This genetic variation is essential for evolution and adaptation.
Basic source of variation in all organisms is mutation .
Most definitly. Asexually reproduced plants are clones of each others so have no genetic variation. Sexually reproduced planst combine the dominant genes from both the partent plants
meiosisHuman recombination
recombination of alleles
sexual
Sexually reproducing organisms inherit their alleles from their parents. Offspring receive one copy of each gene from each parent, leading to genetic variation.
Variations arise due to recombinations(gene rearrangements) ,mutations etc.The former is the principal source of variation in sexually reproducing organisms and the latter is the source of variation in asexual organisms.According to Darwin variation arises due to chance since all the above mentioned process occur in nature spontanuously all organisms show variation
Multicellular organisms reproduce sexually by the combination of genetic material from two parent organisms through processes like fertilization. This allows for genetic diversity and variation in offspring.
As a mammal, a deer would be reproduced internally.
No, dinosaurs reproduced sexually. No vertebrate animals reproduce asexually.
The fruit tree can be asexually reproduced through grafting, budding or sprouting, but the fruit itself would not exist if the tree had not reproduced sexually. The seed within the fruit is the proof of sexual reproduction.
