Mendel's law of independent assortment applies to genes located on:
A. The same chromosome
B. Sex chromosomes only
C. Different non-homologous chromosomes
D. Mitochondrial DNA
Answer: Option C
Solution (By JKExamLibrary)
The law of independent assortment states that alleles of different genes segregate independently of each other during gamete formation, provided the genes are on different non-homologous chromosomes. If genes are linked (on the same chromosome), they tend to be inherited together unless crossing over occurs. This law was derived from Mendel's dihybrid crosses, yielding the 9:3:3:1 ratio.
Explanation:
The iris is the colored part of the eye containing smooth muscles (sphincter and dilator pupillae) that adjust the pupil diameter to control light entry. The cornea and lens focus, retina senses light.
Explanation:
The kidneys sense low oxygen levels and secrete erythropoietin (EPO), which stimulates red blood cell production in the bone marrow. The liver also produces some EPO in fetal life. Bone marrow is the target, not producer.
Explanation:
Stomatal transpiration accounts for about 80-90% of total water loss from plants. Stomata are microscopic pores on leaves, surrounded by guard cells. Cuticular transpiration occurs through the cuticle but is minimal. Lenticular transpiration is through lenticels on woody stems. Hydathodes are involved in guttation, not transpiration. Transpiration creates transpiration pull essential for water ascent in xylem.
