Explanation:
In the given question, the trihybrid cross has been provided for the height trait and it is provided that recessive alleles (aabbcc) contribute 10 cm whereas dominant allele (AABBCC) contribute 22cm.
The height contributed by each dominant allele (A+A+B+B+C+C)= 22cm
The height contributed by each recessive allele (a+a+b+b+c+c)= 10 cm
The dominant genotype is 12 cm taller than recessive genotype which indicates that dominant allele contributes 2 cm.
In trihybrid cross-64 genotype will be formed with these dominant allele based on which the height of the plant will be determined.
The genotype with dominant allele (Height) and F2 progeny are
0 (10cm) - 1/64
1 (12cm)- 6/64
2 (14cm)- 15/64
3 (16 cm)- 20/64
4 (18cm)- 15/64
5 (20 cm)- 6/64
6 (22 cm)- 1/64
It will be negative feedback, because it doesn't happen at a constant rate. Unlike giving birth, lt is considered a positive feedback because the body needs it for delivery.
Question 1. i would say psychology took so long to be recognized because people only thought the problem was in their physical body not their minds and they thought if you just fixed your physical body then your would be fine
The question is incomplete as it does not have the options which are:
a. multiple alleles
b. incompletely dominant
c. codominant
d. pleiotropic
Answer:
Option-D
Explanation:
Pleiotropism is the phenomenon in which one gene is responsible for many phenotypes in the organism.
In the given question, since the gene controls two phenotypes at two different sites as the gene form proteins which act as a catalyst where it speeds up the reaction and in the eye it forms the lens.
Therefore the lens crystalline proteins will be considered the pleiotropic in nature.
Thus, Option-D is the correct answer.
