Characters that are transmitted from parents to offspring during reproduction show

(a) (i) and (ii)

(d) genes ,is The correct option.

(b) genetic material comes from two parents of the same species

Reduction division (meiosis) during gamete formation halves the chromosome number in both male and female gametes. Since these two gametes fuse during fertilisation, the original number of chromosomes (as in...

In sexual reproduction, two individuals having different variations combine their DNA to give rise to a new individual. Therefore, sexual reproduction allows more variations, whereas in asexual reproduction, chance variations...

Asexual reproduction is that type of reproduction in which only single parent is involved. Asexual reproduction takes place by different methods like Budding, Binary fission etc.  → Budding: This type of...

Oviparous animals lay eggs outside their body. As a result, the eggs of these animals are under continuous threat from various environmental factors. On the other hand, in viviparous animals,...

Offspring formed by asexual reproduction are called clones because they are morphologically and genetically similar to the parent.

Halving of chromosomal number takes place during gametogenesis and regaining the 2n number occur as a result of fertilisation.

a. Sexual reproduction brings about variation in the offspring. b. Since gamete formation is preceded by meiosis, genetic recombination occurring during crossing over (meiosis-I), leads to a great deal of variation...
