Heredity is the term use for passing of phenotypic traits from ancestors to next generation or from parents to offspring.
The process of the hereditary:
=> The offspring cell or organism acquires the characteristic of its parent cell of organism.
<span>The study of hereditary is called genetics. It is based on the DNA study of a person’s cell. Mendel’s law shows how this inheriting works </span>
<span>People may inherit physical, emotional or even health problems from their parents or ancestors.</span>

PLS HELP ME!!! In your opinion, what are the limiting factors that might affect the growth or diversity of our ecosystem? Please

I claim light, water and minerals are the limiting factors that might affect the growth or diversity of our ecosystem.

Abiotic factors are the non-living components of an ecosystem and include light, minerals, water etc. These are the vital components without which an ecosystem cannot exist.

Light is essential not only for photosynthesis in plants, but also in maintaining a livable temperature on Earth. Day and night cycles affect and form all the organisms as well as the interactions between them .

Water in itself makes possible the process of photosynthesis in plants as well as the majority of chemical processes in living organisms. Furthermore, makes possible the absorbtion of soil nutrients by the plant roots. Without water, life would not be possible.

Minerals are trace elements that exist in all living organisms and are vital to the existance of life. They can be found in both organic and inorganic combinations and are responsible for the existance and functioning of all mental and physical processis. They are most important in maintaining all physiological process as well as acting as catalysts for many biological reactions.

Ecosystems are complex systems that are built on complex interactions between organisms and their physical environment. In order for any life to exist, certain conditions and requirements need to be fulfilled. Among these, light, water and minerals are vital to the existance of life. Without these three, life as we know it would not be possible. They shape both the ecosystem and the organisms living in a certain area. Their abundance dictates both the growth and diversity of our ecosystem.

Someone please calculate the ratio of offspring please help pleaseeeeeeeeeeeeeeee

Over [174]

Answer:

2. 1 Pink : 1 white

3. 1 Red : 1 Pink

4. 1 Red : 2 Pink : 1 White

Explanation:

This question involves a single gene coding for flower colour in snapdragon plants. The alleles of the gene exhibits incomplete dominance i.e. the red allele (R) ia not completely dominant over the white allele (W), hence an intermediate pink phenotype (RW) is formed. Based on this, a red snapdragon will have genotype, CRCR while a white one will have genotype, CWCW. The intermediate pink phenotype will have a genotype, CRCW.

The image attached to this question shows four crosses between different traits.

In the second cross between a pink (CRCW) and white offspring (CWCW), 2pink and 2white offsprings will be possibly produced in the ratio 1:1.

In the third cross between a red (CRCR) and pink (CRCW) snapdragon, 2 red and 2 Pink offsprings will possibly be produced in a ratio 1:1.

In the fourth cross between a pink (CRCW) and pink (CRCW) snapdragon, red, pink and white offsprings will be produced in the ratio 1:2:1.

See attached image for the complete punnet square. Note that, there was a mistake in the Genotype of the last cross i.e. pink has genotype CRCW not CWCW.
