Grana is the term that describes stacks of thylakoids.
Because l-glucose is toxic in nature.
Gene mutations can be classified in two major ways: These mutations are also called germline mutations because they are present in the parent's egg or sperm cells, which are also called germ cells. When an egg and a sperm cell unite, the resulting fertilized egg cell receives DNA from both parents.
The error takes place when the genes are copied and chromosomes are divided. They can lead to genetic disorders that are inherited.
<h3>What is gene mutation?</h3>
The mutation of the gene is the change in one or more genes that can lead to genetic disorders or illness. The gene disorders are classified in the 2 ways as germline mutations which are present in the parent's cells and are called germ cells. That can take place when the egg of the parent cell and the DNA unit.

Answer:
B- A cleft chin is due to a dominant allele
Explanation:
A husband and wife both having the phenotype for cleft chin and producing an offspring without a cleft chin, indicates heterozygousity in their genotype.
With the heterozygous genotype however, they both expressed the phenotype for cleft chin, indicating that the allele for cleft chin is dominant over the allele coding for normal chin.
Since both parents are heterozygous for cleft lip, the sequence of genotype in their offspring will be:
- 25% chance of having homozygous cleft chin
- 50% chance of having heterozygous cleft chin
- 25% chance of having homozygous normal chin
Because of the dominance of the cleft chin allele, both homozygous and heterozygous forms of the cleft chin allele, will be expressed in the offspring and only the offspring homozygous for normal chin will not express this allele.
