Give two reasons for the appearance of variations among the progeny formed by sexual reproduction.

(c) (i), (ii) and (iii)

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

Asexual reproduction Sexual reproduction (a) Involves only one parent (b) Gametes are not produced (c) No fertilization and zygote formation (d) Meiosis does not occur at any time during reproduction (i) Often involves two parents (ii) Gametes...

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...

Answer: (ii) proper diet is needed for the rapid growth taking place in their body.  Answer: (i) menstruation starts.  Answer: (ii) chapatti, dal, vegetables.   Appearance of moustache and beard.   Appearance of chest...

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...

The tall/short and round/wrinkled seed trait are independently inherited.

Sexual reproduction promotes diversity of characters in the offsprings. It results in new combination of genes.
