Question

A cat gives birth to kittens that do not resemble either parent, while a plant grown from a sapling is similar to its parent plant. What is the reason for this?
A) Kittens develop new features, which help them survive better than the plant offspring.
B) Kittens change themselves according to the environment better than the plant offspring.
C) Kittens receive features from one parent but the plant offspring receives features from both parents.
D) Kittens receive features from both parents but the plant offspring receives features from a single parent.

Answer 1

Answer:

The correct answer would be D) Kittens receive features from both parents but the plant offspring receives features from a single parent.

Cat only reproduces sexually in which male and female parent contribute equal genetic material to the offspring. It leads to the genetic variation in the offspring.

In addition, crossing over takes place during gametogenesis also adds to the genetic variation of the offspring produced by sexual reproduction.

This is the reason that kitten (offspring produced by sexual reproduction) has some genetic variations as compared to the parent and it does not resemble either of the parents.

In contrast, saplings can be done vegetatively through cutting due to saplings receive genetic material from a single parent.

Answer 2

D; kittens receive features from both parents but the plant offspring receives features from a single parent.
