2) Sub-metacentric chromosomes: In sub-metacentric chromosomes, the centromere lies slightly away from the middle region. 3) Acrocentric chromosomes: In acrocentric chromosomes, the centromere is located close to the end of the chromosome. • The ribose sugar and the phosphates form the backbone of a polynucleotide chain with nitrogenous bases linked to sugar moiety and projecting from the backbone. A. Monohybrid cross is a cross between two parents that have one pair of contrasting characters; for example, if pea plant with yellow seed coat is crossed with pea plant having green seed coat then in the F1 generation all the plants produce yellow seeds.

All questions and answers from the Science And Technology Solutions Book of Class 9 Science Chapter 16 are provided here for you for free. Hereditary characters are transferred from parents to offsprings by gene, hence they are said to be structural and functional units of heredity.
B. DNA is a very large single molecule also called as macromolecule. C. The component which is in the nuclei of cells and carries the hereditary characteristics is called chromosome. Leber hereditary optic neuropathy|| Mitochondrial. It is characterised by low haemoglobin count and other symptoms of anaemia such as fatigue and irritability, swelling on hands and legs, pain in joints, constant low grade fever etc. Down's Syndrome: Down's syndrome is caused due to the presence of an additional copy of chromosome 21 (Trisomy of 21). They play a structural and catalytic role during translation. It is a result of replacement of GAG by GUG leading to the substitution of Glu by Val at sixth position of beta globin chain of haemoglobin. It was the first discovered and described chromosomal disorder in humans. Explain Mendel's monohybrid progeny with the help of any one cross.
44+X:Turner syndrome::44+XXY:-.............. DNA fingerprinting is widely used in forensics since DNA of every tissue from an individual has the same degree of polymorphism. Chromosomes are divided into four types based on the position of the centromere. In order to prevent this transmission, people should get their blood examined before marriage to know if they are a carrier of any genetic disorder. Monogenic disorder||Pale skin, white hairs|. Example- a cross between tall and dwarf plant||. The cross in which only two pairs of contrasting characters are involved is known as dihybrid cross. B. Dihybrid cross is a cross between two parents that have two pairs of contrasting characters, for example, a plant having round and yellow seeds is crossed with a plant having green and wrinkled seeds. Science And Technology Solutions Solutions for Class 9 Science Chapter 16 Heredity And Variation are provided here with simple step-by-step explanations. As a result, the chromosome has only one arm. View NCERT Solutions for all chapters of Class 9. Question 5: How are the items in groups A, B and C inter-releated? C. |Monohybrid cross||Dihybrid cross|. C. DNA fingerprinting is a method for comparing the DNA sequences of any two individuals.
Rather, we sholud support and accept people with such disorders, so that they can live a normal life. The total number of chromosomes in people affected with Down's syndrome becomes 47. • Two types of nitrogenous bases are present i. e. Purines (Adenine and Guanine) and Pyrimidines (Cytosine and Uracil). A dihybrid cross is useful in studying the assortment of the offspring. Genetic disorders are caused by changes in DNA sequences which can only be passed from one generation to another under specific circumstances. 4) Telocentric chromosomes: In telocentric chromosomes, the centromere is present at the terminal end. D. A RNA nucleotide has three main components − a nitrogenous base, a ribose sugar and a phosphate group. 9% of the base sequences in all human beings are identical.
Question 7: Complete the tree diagram below based on types of hereditary disorders. E. Organisms produced through sexual reproduction show major variations. E. It is necessary for people to have their blood examined before marriage because the genetic disorders are transmitted only by reproduction. Nitrogen bases are attached sugar from inwards that extends to join hydrogen bond and the complimentary nitrogenous base from other strand. There are 3 types of RNA: 3. rRNA (ribosomal RNA) − These are the work benches of translation. DNA fingerprinting forms the basis of paternity testing since a child inherits polymorphism from both its parents. Effect on blood-glucose level. Some of the examples of monogenic disorders are sickle cell anemia, cystic fibrosis, polycystic kidney etc. These solutions for Heredity And Variation are extremely popular among Class 9 students for Science Heredity And Variation Solutions come handy for quickly completing your homework and preparing for exams. • Every nucleotide residue has an additional −OH group present at 2' -position in the ribose.
