Answer:
The most appropriate reason for the presence of genetic diversity among siblings would be an option A.
Crossing over is an event that place during pachytene stage of prophase I. During this event, the genetic material is exchanged between the non-sister chromatids of homologous chromosomes.
It results in the production of a new combination of alleles in gametes. These combinations can be different from either parent.
So, when genetically varied gametes fused to form a zygote, it results in the development of genetic variation among population including siblings.
Dry matter is what remains after all of the water is evaporated out of a feed: grain and fresh or dried forages. Fresh pasture has high water content and will have a lower percentage of dry matter than an equivalent weight of dryer feed, such as hay or grain. Dry matter is an indicator of the amount of nutrients that are available to the animal in a particular feed.
Livestock need to consume a certain amount of dry matter per day (measured in lbs or kg/day) to maintain health and production. The daily amount of dry matter needed depends upon several factors including, weight and stage of production (e.g., lactating, pregnant, weaning, finishing). Dry matter intake (DMI) can be estimated by using published reference tables that provide the percent dry matter in various dry (hay and grain), fresh, and ensiled feeds. There are also methods to measure the actual dry matter in feed.
Under the NOP regulations, ruminants must obtain at least 30% of their dry matter intake (DMI) from grazing on pasture during the grazing season.
Answer:
From the given Options, Option C is correct.
the inheritance of the alleles from each parent is completely random but in a population, there may be natural selective pressure from the environment to favor different levels of expression
Explanation:
The evolutionary basis of human skin color stems far back to the genetic mutations involved in skin pigmentation. Although the diversity of skin color is a characteristic trait of humans, These variants and their evolution reveal that the history of skin color is much older than previously thought.
The evolution of various variations in the human skin color is a result of selective forces which is an environmental factor that favors various levels of expression. Thus, the best option that explains the basis of human skin color in terms of evolutionary trend is Option C.
