An individual always has two alleles for the same gene (one on each chromosome). Which statement is true?
a)A person's two alleles are always different
b)A person's two alleles are always the same.
C)A person's two alleles may be the same, and they may be different
Answer:
A
Explanation:
An individual always has two alleles for the same gene (one on each chromosome). The statement which is true is "a person's two alleles may be the same, and they may be different". Thus, the correct option is C.
What are alleles?An allele can be referred to as an alternative form of a gene. An allele is located at a specific position on a specific chromosome. These alleles can be passed on from the parents generation to their offspring through the process of sexual reproduction.
The presence of two identical alleles at a particular gene locus (chromosome) is referred to as a homozygous genotype. This may include two normal alleles or two alleles that have the same variant. The presence of two different alleles at a particular gene locus is referred to as a heterozygous genotype.
Therefore, the correct option is C.

Are genetic mutations avoidable? Explain.
Answer:
Mutations happen in our cells all the time. It's actually how all humans grow and change. The vast majority of mutations are harmless. Thus, they aren't avoidable.
Mutations occur in our cells all the time. It's how all humans grow and transform. The vast bulk of mutations is harmless. Therefore, they aren't avoidable.
What are Genetic Mutations?
The permanent transmissible difference in the genetic material. An individual exhibiting such a transformation. A point mutation is a mutation resulting from a modification in a single bottom pair in the DNA molecule.
Any alteration in a nucleotide succession of DNA is called a mutation. Chromosomal, dependent, and gene mutations are some of the illustrations of different kinds of genetic mutations.
So, Therefore, They aren't avoidable.

Children inherit half of their genes from parents. Explain Why?
Answer:
This is because the two parents share one or more common ancestors and so carry some of the same genetic material. If both partners carry the same inherited gene change, their children are more likely to have a genetic condition.
Answer:
yes
Explanation:
The chromosomes in cells line up in pairs and exchange bits of genetic material before forming an egg or sperm cell. Each mature egg and sperm then has its own specific combination of genes, which means children will inherit a slightly different set of DNA from each parent.

The following are density-dependent factors are:
b. disease
c. food supply
Density-dependent factors:Density dependant elements can have either a positive or a negative relationship to populace size. With a positive relationship, these restricting variables increment with the size of the populace and breaking point development as populace size increments.
This includes disease, predation, and food supply.

Mammalian erythrocyte lacks nucleus. Why? Give reason.
Explanation:
Complete answer:
A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules. Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion. Young mammalian RBCs are nucleated.
