How to Prepare KPK Board Classes Short Question Answer at Gotest
- Just Open the desired Class and subject which you want to prepare.
- You have Green bars which are Questions of that subject Chapter. Just click on Bar, it slides down and you can get the right answer to those questions.
- Blood group of man IA IB(AB)
- Blood group of female I0 I0(O)
Or by punnet square
IA IB
| I0 | IA I0 | IB I0 |
| I0 | IA I0 | IB I0 |
= 50% of the offspring will be blood group A.
= 50% of the offspring will be blood group B.
In crossing over segments of homologous chromosomes are exchange in result of which a new chromosome of different genes are formed which results in variation in the offspring.
Chromosome is composed of DNA and proteins [ histone ]. The DNA duplex is coiled around the core of 8 histone proteins forming a complex structure called nucleosomes.
Nucleosomes are arranged in the from of beads in a linear fission on a DNA and then this string of beads is so arranged in compact from that it gives chromatin structure and form chromosome.
Formers and breeders allowed only the plants and animals with desirable characteristic to reproduce causing the education of farm stock. This process is called artificial selection.
Examples: 1) The major cereals ( rice, wheat, maize, sorghum and millet) were all developed from will grasses by artificial selection.
2) Farmers have cultivated numerous popular crops from will mustard i.e Brocli ( ), cabbage ( ), kale ( ), cauliflower ( )
Difference between different types of dominant relations:
1) Complete Dominance:
In complete dominance one allele is completely dominant over the other allele i.e tall (T) is completely dominant over dwarf (t).
2) incomplete Dominance:
In this case a given allele does not completely mask (hide) the action of second allele, rather they interact such a way that heterozyate phenotype is a blending (mixing of both).
Example: The inheritance of flower colour in mirabilis jalapa ( Four O’ clock plant) is an example of incomplete dominance.
3) Co-dominance:
In this case different alleles of a gene that are both expressed in a heterozygote condition are known as co-dominance.
Example:
ABO blood group system in human.
| Gene type | Phenotype |
| IA IA | Blood group ‘A’ |
| IBIB | Blood group ‘B’ |
| IB i | Blood group ‘B’ |
| IAi | Blood group ‘A’ |
| i i | Blood group ‘O’ |
| IA IB | Blood group ‘AB’ |
