The extra X chromosome is received from mother.
<h3><u>Explanation</u>:</h3>
Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.
Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind.
Nucleic acids carry this information because they help make DNA
Answer:
1) 5 kingdom system of classification is a type of classification in which all the living organisms are classified into 5 kingdoms i. e. protista, monera, fungi, plantae and animalia.
2) Plants are autotrophic organisms while animals are heterotrophic. Plants have cell wall while cell wall is absent in animal. Plants are fixed while animals move from place to place.
3) Both plants and animals are made of cell. Both plants and animals are multicellular organisms. Both plants and animals reproduce.
4) Plants make their own food while fungi are unable to make their own food. Plant cell wall is made of cellulose while fungi cell wall is made of chitin.

Have A Good Day!!!
Complex organisms need cells that can perform many different functions. they need to be supported on a cellular level. Without specialized cells you they won't be able to perform different functions.
