State the mendelian principle which can be driverd from a dihybrid cross net from monohybrid cross |
|
Answer» aw of the Mendel or Law of the Independent Assortment can be derived from the Dihybrid cross and not from the monohybrid cross. Monohybrid cross can be only use to derive the Law of Dominance and Law of the Segregation. (First and second law)Law of Independent Assortment of the Mendel says that, '' The Law of Independent Assortment is a PRINCIPLE of inheritance that states that each heritable allele (contrasting PAIR of GENE) is inherited independently of one ANOTHER. ''Phenotype ratio = 9 : 3 : 3 : 1Genotype Ratio = 4 : 2 : 2 : 1 : 1 : 2 : 1 : 2 : 1Hope it HELPS. |

What is phospholipid? |
|
Answer» :-In general terms, a Phospholipid can be defined as a "Amphiatic molecule" with both Hydrophillic (soluble in water) and Hydrophobic (insoluble in water) regions. Extra Information :-~~~~~~~~~~~~~~~~~~~~~~~~PHOSPHOLIPIDS consist of FATTY acids.Phospholipids consist of an Alcohol (OH) Group.Phospholipids mainly consist of "Phosphate groups". Phospholipids are important constituent units of the cell MEMBRANE. Phospholipids CONTAIN both "Polar" and "Non-Polar" portions. Some Phospholipids such as "Lecithin" have a nitrogenous compound "Choline", attached to them. Lecithin (Phospholipid) is produced commercially from "Soyabean SEEDS". Lecithin is considered to be an excellent Emulsifying agent. |

What is parthenogenesis with suitable examples |
|
Answer» ogenesis is a type of asexual reproduction in which the offspring develops from unfertilized eggs. It is particularly common amongst arthropods and rotifers, can also be found in some species of fish, AMPHIBIANS, birds, and REPTILES, but not in mammals. Parthenogenetic development also occurs in some plants species, such as roses and orange trees.Most animal species that reproduce parthenogenetically also display a phase of sexual behaviour and sexual reproduction. In most cases, parthenogenetic reproduction occurs when environmental conditions are favourable and there is plenty of food that can sustain the generation of large numbers of INDIVIDUALS in a short period of time.When external conditions change and food supplies become less abundant, or when the environment becomes unpredictable, these species shift to a sexual mode of reproduction. Although sexual reproduction is considerably slower and generates fewer organisms, it gives rise to individuals containing variations in their genetic material. Some of these individuals might be at an advantage over their predecessors, because they might be more able to adapt to new conditions.In some species of insects, such as the aphids, parthenogenetic reproduction occurs in the spring and summer, when conditions are favourable for rapid population growth. As time goes by and conditions become less favourable, the parthenogenetically born individuals mate and lay fertilized eggs. These eggs hatch the following spring, when conditions are again favourable for another cycle of parthenogenetic reproduction.In some species of ants, bees, and wasps, the ability to reproduce both sexually and asexually is part of the mechanism establishing sexual differences.Usually, females develop from unfertilized eggs, containing only half of the genetic material of the mother, whereas males develop from fertilized eggs, containing the genetic contributions of both mother and father.In other species of insects, such as the rotifers, females produce unfertilized eggs that develop into females during the spring and summer. This process goes on for several generations. During the autumn, smaller eggs are laid, which develop into individuals lacking a digestive system, but capable of secreting sperm. These individuals mate with females, who then produce highly resistant, fertilized eggs that remain viable during long periods of UNFAVOURABLE conditions. These eggs hatch in the following spring, GIVING rise only to females, who then engage in a new period of parthenogenetic reproduction.HOPE IT HELPS..... |
