Answer: During segregation,there is separation of two coexisting alleles for a specific trait at the point of meiosis in an individual,such that each gamete receives only one of two alleles.Alleles recombine during random fertilization of gametes when zygote is formed.
Explanation:
Gregor Mendel laid foundation of classical genetics by formulating his law i.e LAW OF SEGREGATION.He performed a series of experiments on pea plants.he focused on 7 of their traits.He proposed that such traits were determined by particular factors he termed "ELEMENTEN". these factors carrying hereditary information were transmitted from parents to offspring through gametes .He inferred that factors of pair of alleles separate from each other during gamete formation so that each gamete got only one allele for each trait.Fertilization was random.MENDEL compared results of all the 7 separately studied characters and found them similar to formulate his law of segregation as stated above !
Answer:
prokaryotic: A prokaryote is a single celled organism that does not have a nucleus or membrane bound organelled and its dna is in the cytoplasm. They also cant undergo mitosis because they dont have a nucleus. they are most likely to be unicellular
examples: archea and bacteria
eukaryotic:
A eukaryotic cell is an organism made up of cell that contain their dna in a nucleus. Eukaryotic cells contain membrane bound organelles as well as ribosomes.not all of them are the same though. mst of them are multicellular and go through mitosis
examples: fungi, plants, animals.
Answer:
The accessory pigments like carotene & xanthophyll necessary to have in green plants is chlorophyll
Explanation:
Various pigments present in the plants helps in the absorption of the light, at photosynthesis. They acts as helpers to the plants. Chlorophyll helps in the green plants for absorption of light through which they can prepare their own food. The electrons in the molecular level of chemical structure of the pigment moves at certain energy levels. The chlorophyll is again divided into different types i.e. chlorophyll a,b,c,d. In case of plants chlorophyll a and chlorophyll b are the most important.
Answer:
C
Explanation:
Height in humans is influenced by numerous loci and has a relatively smooth distribution. It is thus a quantitative or continuous trait.
A quantitative trait locus (QTL) is a DNA territory correlated with a specific phenotypic trait that differs in extent and can be linked to polygenic effects, i.e. the product of two or more genes, and their habitat.
