Answer:

the answer should be A

Explanation:

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.

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.

Explanation:

Environmental factors determine all genetic traits. Why? So the organism that is gaining the trait has a better chance of survival or to be more specific a better chance at adapting to their environment. Let me give you an example, the long necks on a giraffe. The diet of a giraffe consist of mostly acacia leaves which are leaves that are on the top of a tree. This environmental factor is why giraffes have long neck so they can get to the leaves of the tree. If they did not have long necks giraffes probably would´nt survive

Now let me give you an example that is related to evolution

Evolution is the change in the characteristics of a species over several generations

An example of this happening can be shown in mosquitoes

People were using DDT (which is an insecticide used to kill bugs) on mosquitoes to harm them. Many of the mosquitoes had died but the remaining were able to produce offspring that had mutations. These mutations caused the mosquitoes to be resistant to the insecticide. This shows another example of environmental factors having an influence on genetic traits. The DDT spray was the environmental factor and the mosquito being able to produce offspring that were resistant the the insecticide is the outcome from the influence.

Answer:

Aside from reducing fish stocks, unsustainable fishing practices can have other negative impacts on the marine environment. For example, some fishing techniques such as dredging and trawling can cause widespread damage to marine habitats and organisms living on the sea floor

➣ If humans will continuesely kill mass of fishes for their own benefit it will disturb the ecosystem of the maine habitat . In the places like ponds and rivers the quantity of fishes is not that much and if human will kill catch all the fishes the growth of alage plant will increase rapidly as there is no organism is there to eat them and the big predator also stave for hunger as there is no food for them

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.

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.

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.

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.
