  • They are natural and not man-made.
  • Inorganic i.e. not made by any organism.
  • Minerals are solids, not liquid or gas.
  • They have a definite chemical structure.
  • The atoms in minerals are arranged systematically and are arranged in a repeated pattern.

Minerals are natural and we use it in our day to day life. Products like salt and even a pencil have minerals. Also, these minerals help the parts in the human body to grow faster and function properly.

A plant contains the alleles Gg for green pod
Viefleur [7K]

Given:

Allele for green pod colour = Gg (Heterozygous)

Allele for Yellow pod colour = gg (Homozygous)

Explanation:

Parents: Gg x   gg

When this two parent are crossed, it leads to the following F1 generation (off springs):

<em>• Gg (green colour pod) </em>

<em>• Gg (Green colour pod) </em>

<em>• gg (Yellow colour pod) </em>

<em>• gg (Yellow colour pod) </em>

Form the produced offspring it can be inferred that the allele combination for green colour pod is Gg. Among the four off springs obtained 2/4 are green colour pod and 2/4 are yellow colour pod.

postnew [5]

Answer:

The ABO blood group is the case of co-dominance or multiple allelism. Co-dominance may be defined as a non Mendelian inheritance in which both the alleles can express themselves in the heterozygous condition.

The person with blood type A has two possible genotypes with IA IA or IA i.

The person with blood type B has two possible genotype with IB IB or IBi.

The person with blood type has genotype of IAIB.

The person with blood type O has possible genotype is ii.

Thus, there are total six possible genotype of blood group exist in human population.
