Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"
A) complete dominance
B) incomplete dominance
C) codominance
D) epistasis
E) incomplete penetrance
Answer:
B) incomplete dominance
Explanation:
Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.
For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".

fossils, the preserved remains of animal and plant life, are mostly found embedded in sedimentary rocks. Of the sedimentary rocks, most fossils occur in shale, limestone and sandstone. Earth contains three types of rocks: metamorphic, igneous and sedimentary.

Answer:
C. glycosidic bond angles and structure of pyrimidine bases.
Explanation:
The minor groove contains less information about the identity of base pairs than the major groove because of the glycosidic bond angles and geometry of base pairings. glycosidic bond angles and structure of pyrimidine bases.
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water.
Answer:
Pulo ng Luzon.
Paliwanag:
Ang isla ng Luzon sa Pilipinas ay mayroong anim na pinaka-aktibong mga bulkan na matatagpuan. Ang islang ito ay isinasaalang-alang bilang pangunahing isla ng Pilipinas na mayroong mga aktibong bulkan. Ang aktibong bulkan ay tumutukoy sa mga bulkan na pinagmulan ng pagsabog ng Lava at iba pang mga gas. Sa pagsabog na ito, malaki ang pinsala na nagaganap sa mga halaman at pag-aari ng mga tao kung kaya't ang islang ito ay mapanganib na tirahan.
