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.
Polymorphism in Hydrozoa refers to the occurrence of different morphological forms within the same species, particularly evident in the colonial organisms of this class. Hydrozoans typically exhibit two main forms: the polyp, which is sessile and often reproduces asexually, and the medusa, which is free-swimming and primarily reproduces sexually. This dual life cycle allows for greater adaptability and survival in varying environments. The different forms often have specialized functions, contributing to the colony's overall efficiency and reproductive success.
No, sexually transmitted diseases (STDs) can affect anyone who is sexually active, regardless of their hygiene or lifestyle choices. STDs are transmitted through sexual contact, and anyone can be at risk if they engage in unprotected sex or have multiple partners. It's important to practice safe sex and get regular check-ups to reduce the risk of STDs. Misconceptions about STDs often lead to stigma, but they can affect individuals from all backgrounds.
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.
