Neurons and muscle cells perform different functions. in the body, these cells have the same . the function of muscle cells is , while the function of neurons is to send nerve signals. nextreset

The first blank can be correctly filled up with the same genetic material and the second blank can be correctly filled up with to contract.

All the cells of the body such as muscle cells, nerve cell, cardiac cell, blood cell et cetera contain the same genetic material. They become specialized cell as a result of cell differentiation.

The function of the muscle cells is to contract which helps in locomotion and movement. Skeletal muscles help in locomotion and smooth muscles help in the function of internal organs such as uterus muscle contracts which help in delivering the baby.

The function of the nerve cells is to transmit signals from receptors to the central nervous system (CNS) and from CNS to effector organs.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
