The mitochondria is the powerhouse, or in a sense the brain of the cell. The plant would be unable to (a) carry out respiration
<span>During mitosis the genetic material from one cell is replicated and an entirely new cell is produced. The amount of genetic information is very great and it must be coiled up into histones to prevent the tangling and breaking of genetic material during the process of mitosis.</span>
The first line of defense, <span>includes physical and chemical barriers. These include your skin, tears, mucus, cilia, stomach acid, urine flow, bacteria and white blood cells called necrophiliacs.</span>
Answer:
Phenotypic ratio - 3 Freckes : 1 No freckles
Explanation:
This question represents a monohybrid cross i.e. involving a single gene coding for possession or not of freckles. The allele for possession of freckles (F) is dominant over the allele for no freckles (f).
In a cross between two HETEROZYGOUS parents i.e. Ff × Ff, each parent will produce gametes with alleles F and f respectively. Using a punnet square (see attached image), four possible offsprings will be produced with genotypes: FF, Ff, Ff and ff.
Based on this genotypes, the phenotypic ratio of the offsprings will be 3:1 where 3 offsprings will possess freckles and 1 will have no freckles.
