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.
Answer:
a) Inbreeding
b) Decreased
Explanation:
Florida panther is considered an endangered species that is found in very few numbers in the environment.
In the given question,
a) The Florida panther scattered in the mountains which could affect the flow of the genes (migration). When it mated with the other sub-species, it could have led to the inbreeding.
b) Since the lion scattered in the mountains, the gene flow could have occurred and this could have decreased the genetic variation in the population of the Panthers.
By natural selection, the nature of species gradually changes to become adapted to the environments. This variation of traits in a population is what gives the organisms the ability to survive environmental changes. If not the species becomes extinct.
Rain. umm it says that I have to have 20 characters
The sign is incomplete so I will outline the rules for shading:
First, make y the subject of the formula. Then,
If the sign of y _ bx + c is:
≥ then you form a solid line and shade above it
≤ then you form a solid line and shade below it
> then you form a dotted line and shade above it
< then you form a dotted line and shade below it
