Answer:
Predict the possible genotypes and phenotypes percentages for the
offspring produced from the cross below if albinism is recessive in
humans. Albino male x Heterozygous female
aa X Aa = Aa, aa, Aa, aa
Explanation:
From the crossing above, it is right to say that albinism and non-albinism occur in a 50-50 ratio i.e 50% each. The genotype shows that there is 50% homozygous recessive albinism while there is also 50% heterozygous non-albinism. The phenotype reflects that there no dominance of albinism or non-albinism, they both share equal phenotypic characteristics
Answer;
-Projection level
-Projection level controls intermediate relay for incoming and outgoing neurons.
Explanation;
The levels of motor control include; segmental level, projection level and precommand level.
-The segmental level is the lowest level of motor hierarchy. It consists of segmental circuits of the spinal cord, Its circuits control locomotion and specific, oft-repeated motor activity. These circuits are called central pattern generators (CPGs).
The projection level consists of: Cortical motor areas that produce the direct (pyramidal) system, and Brain stem motor areas that oversee the indirect (multineuronal) system
. It helps control reflex and fixed-pattern activity and houses command neurons that modify the segmental apparatus.
Precommand level; Cerebellar and basal nuclei systems that:
-Regulates motor activity, precisely start or stop movements, coordinate movements with posture, Block unwanted movements
, and Monitor muscle tone.
