Answer:
•The relationship between the twist and the wild type flower in the first crossing is known as a COMPLETE DOMINANCE
•The relationship between the forked and the wild type flower in the second crossing is also known as a COMPLETE DOMINANCE
•The relationship between the pale and the wild type flower in the third crossing is known as an INCOMPLETE DOMINANCE
Explanation:
A complete dominance is characterised by having one of the genes (the dominant gene) in an heterozygous condition, completely masking the effect of the other (the recessive gene) of thesame allelic pair. E.g. if the genes in allelic is represented with Aa, "A" is said to completely dominate "a" if it does not allow "a" to Express itself phenotypically.
The heterozygous condition is always the result of the F1 generation
and the F2 generation of a Complete dominance is always characterised by a phenotypic ratio of 3:1 which is in line with the results gotten from the first crossing and the second crossing as stated in the question.
An complete dominance is characterised by having an intermediate progeny in the F1 generation which was evident in the result of the third crossing. Also a phenotypic ratio of 1:2:1 in the F2 generation is also a characteristic feature of an Incomplete dominance relationship which was also evident in the third crossing.
The very first one is the answer-
Abiotic changes have the ability to dictate biotic ones. This can be caused by humans.
For example: an abiotic thing can be an element like water. If the water in a lake gets poisoned by chemical compounds, this is an abiotic change. However, since the lake is now poisoned it’ll likely harm or even kill fish, bacteria, algae, and any other wildlife living within the lake. It doesn’t stop there though, without the lake surrounding animals won’t have clean water to drink, they can now die from either the poisoning, dehydration, or starvation if they lived off of the aquatic life from the lake.
Answer:
Explanation:
Sensory receptors are specialized neurons that respond to specific types of stimuli. When sensory information is detected by a sensory receptor, sensation has occurred. For example, light that enters the eye causes chemical changes in cells that line the back of the eye.
Answer:
all the black ones are aa all the white are Aa
it is a recessive trait
and 50% odds for the progeny to have it
Explanation:
Answer: "The synovial fluid in my joint capsule acts as a lubricant and helps the movement of the joint's articulating surfaces."
Explanation:
Synovial fluid is also called Synovia. It is produced by the synovial membrane. It is a thick liquid found in the cavities of synovial joints. It's function is to reduce friction by acting as a natural lubricant between the articular cartilage of synovial joints and allows ease of movement, they act as shock absorber and nourishment in the joints. Each of the joints contain synovial fluid.
