13) The phenotype of an organism is

Which of the following is NOT a major abiotic component of the environment? Fire Rainfall Winter Temperatures Nutrient Levels None of the above The phenotype of an organism is The observable properties of the organism The combination of alleles possessed by the organism A heritable property of the organism The fundamental particle of heredity A stretch of DNA that codes for a protein In humans, the achondroplasia condition is caused by a dominant (A) allele. Homozygotes for the dominant allele (AA) die before birth. Homozygous recessive individuals (AA) are normal, with regular stature. Heterozygous individuals (Aa) have a common form of dwarfism, having short stature and relatively short limbs, and large heads relative to their bodies. A man with dwarfism marries a dwarf and they have children. What proportion of the surviving progeny will achondroplaic dwarves? 9/16 3/4 100% 2/3 not enough info to tell. The presence of short stature and unusual proportions is an example of which of the following phenomena? epistasis codominance pleiotropy incomplete dominance none of the above If white flowers are recessive to purple flowers, if two white-flowered peas mate, what proportion of the offspring would be white-flowered? 0 1.0 3/16 9/16 can't tell

Explanation / Answer

12. In the environment, abiotic components or abiotic factors are non-living physical and chemical parts of the environment that affect living things or organisms and the functioning of ecosystems.

In the environment, the major abiotic factors can include light, temperature, water, humidity, radiation, soil, and atmosphere. All of these factors affect different organisms to different levels.

Hence, the correct answer is the option (E).

13. The phenotype is the observable physical or biochemical characteristics of an individual organism, determined by both environmental influences and genetic make-up. For example, weight height, and skin color.

Hence, the correct answer is the option (A).
