How does mutation relate to variation

Anastasy [175]

Answer:

Mutation is the source for new genetic variation: Genetic variation is brought about by random mutation. Without mutation, genetic variation cannot occur. Mutation is a change in the genetic code in DNA and can lead to a change in the protein that is coded for that segment of DNA.

Explanation:

Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

kramer

Answer:

C6H6 - organic compound

K - element

Cl2 - inorganic elemental molecule

SO2 - inorganic compound

Explanation:

An organic compound contains carbon and hydrogen bonded covalently . Sometimes other atoms aside from carbon and hydrogen called heteroatoms are also found in organic compounds. C6H6 is an organic compound.

Elements are found in periodic table. They always occur in uncombined state. K is an element.

Cl2 is an inorganic elemental molecule containing two chlorine atoms bonded covalently.

SO2 is an inorganic compound composed of sulphur and oxygen bound covalently. Mnay inorganic compounds do not contain carbon

Use the probability method to calculate the genotypes and genotypic proportions of a cross between AABBCc and Aabbcc parents.

lora16 [44]

For this, you need to use Punnett squares.

You know the genotype of the parents, and for the cross, you need to separate into two alleles, both genes.

AABBCc divided like ABC and ABc.

Aabbcc divided like Abc and abc.

Now you can cross them, and all probabilities will be:

AABbCc, AaBbCc, AABbcc and AaBbcc

So, you could say 25% of the offspring will be AaBbCc, 25% AaBbcc, 25% AABbCc, and 25% AABbcc
