Anthocyanin is a pigment that gives flowers and leaves purple colors. The M gene codes for a transcription factor (Myb) that pro
motes expression of an enzyme that produces anthocyanin. The W gene codes for a different enzyme (Chs) that allows anthocyanin to be deposited in plant leaves and flowers. The dominant phenotype is the production of functional Myb and Chs. Use this information to answer the following question. Plants that have the mm genotype do not show any purple color. What is the best explanation for why this is?
Anthocyanin is not produced in plant cells with the genotype mm.
As you can see from the question above, anthocyanin is responsible for the purple color of the flowers. Anthocyanin is encoded by the M gene, which is a dominant gene. Because it is a dominant gene, we know that it will be expressed in plants with the Mm and MM genotype, but will not be encoded by plants with the mm genotype. With this we can conclude that plants that have the mm genotype do not have purple color, because anthocyanin is not produced in the plant cells of these plants, since they do not have the M gene.
Various species display various degrees of resilience for polyploidy. For instance,<em> polyploids structure </em>at moderately high recurrence in <em>blossoming plants (1 for every 100,000 people)</em>, recommending that plants have a strikingly high <em>resistance for polyploidy.</em> This is likewise the situation for certain types of fish and frogs.
Polyploidy is normal in plants than in creatures in light of the fact that in creatures sex assurance component includes <em>number and type sex chromosomes. </em>
Polyploidy will meddle with this component and subsequently it is seen once in a while in animals.This vegetative proliferation empowers increase of <em>polyploid plants. </em>
Chromosomes can be divided by by their such as <em>size,banding design number, centromere position. </em>
<em>Autosomes or "body chromosomes"</em> (the entirety of the non–sex chromosomes) are commonly found in the human karyotype sorted out in rough request of size from biggest (chromosome 1) to littlest (chromosome 22).
The number and presence of chromosomes in a phone is known as a karyotype.
A karyotype must be seen and examined with a magnifying lens. Karyotype investigation can uncover anomalies, for example, <em>missing chromosomes, additional chromosomes, erasures, duplications, and translocations.</em>
Your backyard is a great example of an ecosystem. You may have a lawn, which sprouts mushrooms, is home to squirrels and birds, and other forms of life.
