When you cross two hybrids, the results always come in a 3:1 ratio as follows:
3 is the inheritance of at least 1 dominant allele
1 is the inheritance of two recessive alleles
Punnet Squares are very useful!
<u>T t </u>
T | TT | Tt |
t |<u> Tt | tt </u>|
Three out of 4 boxes have offspring that express the dominant trait (tall plants) and 1 out of 4 boxes expresses only the recessive trait (short plants).
Hope this helps! :)
Answer:
C- Dominant, but not sex-linked
Explanation:
The disorder is not sex-linked because almost equal numbers of people have Pinocchio nose syndrome. If the disorder was sex linked you would have way more men than women having the disorder.
You can tell that the genetic disorder is dominant because there is a 3:1 ratio for those who have the disorder.
36 out of 47 men ≈0.765
37 out of 53 women≈0.69
These numbers approximate a 3:1 ratio (even if it's not exact), meaning that the disorder is most likely dominant
Answer: Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.
Explanation:
Answer:
- light positioning: c. Extrinsic muscles; d. Pupil
- sensory processing: a. Photoreceptors; b. Occipital cortex; e. Bipolar cells
Explanation:
Extrinsic (extraocular) muscles are muscles that modulate both eye movement and position, whereas intrinsic (intraocular) muscles are muscles that focus the eye and control how much light enters into the eye. The pupil is the black center of the eye within the iris through which light passes before being focused onto the retina. Photoreceptors are specialized neurons located in the retina that respond to light, converting it into electrical signals that can stimulate biological processes. Photoreceptors in the retina are divided into two categories 1-rods (responsible for vision at low light levels), and 2-cones (active at higher light). Bipolar cells are neurons that transmit signals from the photoreceptors to the ganglion cells, thereby processing light signals received from rods and cones. The occipital cortex is a brain region that represents the visual processing center and contains most of the anatomical region of the visual cortex.
Explanation:
Reproduction in Fishes. Nearly all fish reproduce by sexual reproduction - the fusion of sperm produced from testes and eggs produced from ovaries. ... Fertilization is external in most fish species. Large quantities of eggs and sperm are simultaneously released into the water by females and males.
