Identifying the genetic sex of a child is based on finding intracellular Barr bodies that consist of inactive chromatin material.
Inactive chromatin material is the one where no transcription takes place. It is also known by the name heterochromatin. It appears as a dark condensed form in the chromatin.
Barr bodies are the inactive X chromosomes. These are mad inactive by a process termed as lyonization. It is essential to make the chromosome inactive in organisms with XY type of sex determination. They are present at the periphery of the nucleus. Inactivation of X chromosome makes the amount of X chromosomes equal in both, males and females.

Answer:
66.7m/s²
Explanation:
initial velocity(V)=54m/s
Final velocity(U)=4m/s²
Time taken(t)= 0.75 seconds
Acceleration is unknown
To find the acceleration we use this formula
a=v-u/t
a=54-4/0.75
a=50/0.75
a=66.666666
since it is acceleration we use the symbol m/s² after approximating to 1 decimal place
a=66.7m/s²

Answer:
In cross-pollinating plants that either produce yellow or green pea seeds exclusively, Mendel found that the first offspring generation (f1) always has yellow seeds. ... that a trait may not show up in an individual but can still be passed on to the next generation.
