Answer:
EEG or electroencephalography
Explanation:
Electroencephalography or EEG is a technique to measure all the brain waves. These waves are occurred due to emotion, stress, or any change in stimuli received by the brain.
This is a technique where small metals are used to attach in the brain and detects the brain electrons wave. By using this technique individuals mental disorders like epilepsy and sleep disorders can be detected.
EEG measures the electrical activity of the brain. It also detects the activity of a large group of neurons.
Music therapy is also used with EEG to detect the anxiety, depression, of a person. As music induces strong emotions in a person, EEG is detected with music therapy.
But there are some limitations in this technique - it only detects the changes in the brain waves in the cortex, as the metals are attached to the skull. It can not measure deeper brain waves.
EEG also can't tell the exact location, where the brain wave changes. Because in a single time, it records several neuronal waves.
Besides these limitations, EEG is a useful technique to detect mental disorders.
The dominant trait is hornless.
If this is correct, then the original bull is a heterozygote:
H = hornless
h = horned
Bull is Hh
Cross 1: Hh x hh (horned female) - offspring is hh (horned)
Cross 2: Hh x Hh (hornless female) - offspring is hh (horned)
Cross 3: Hh x hh (horned female) - offspring is Hh (hornless)
Cross 3 is the key to confirming this because the only way to get a hornless offspring would be if hornless is recessive.
Answer:
Phenotypic ratio: 0 Red : 4 Pink : 0 White
Genotypic ratio: 0RR : 4RR' : 0R'R'
Explanation:
This question involves a single gene coding for flower colour in Japanese four o'clock plants. The allele for red color (R) exhibits incomplete dominance over the allele for white color (R'), hence, they form a hybrid (RR') that is blending of both phenotypes (Pink).
In a cross between a red plant (RR) and white plant (R'R'), red and white four o'clock plant will produce gametes R and R' respectively. Using these gametes in a punnet square (see attached image), four possible offsprings that all have a genotype: RR' will be produced. This means that all offsprings of this cross are pink colored.
Therefore,
Genotypic ratio= 0RR : 4RR' : 0R'R'
Phenotypic ratio= 0Red : 4Pink : 0White
