Ok so imma make this cleaner to make it earlier to understand. :)
H for brown hair
h for red hair

Mother: Hh
(It’s given)
Father: hh
(Saying that it’s isn’t brown; let’s put this instead, we are trying to find the gene for red hair.)

So in the punnet square below, it is shown that there is a 50/50 chance for the offspring to have red hair.
Ration is 1:1.
But there is also another probability for the offspring to be like their mother, have the dominant gene of black hair overruling the recessive gene of red hair.

Probability is 50% Brown and 50% Red.
I think the ratio might be 1:1

A bat species (species 1) lives in a city. Another bat species (species 2) established a population in that same city after some

ddd [48]

Answer:

Roosting areas in buildings of any height are the resource partitioning of both bat species.

Explanation:

The fundamental niche refers only to physic conditions in which a species can live and survive in the absence of any interaction with other species.

The realized niche refers to the restricted conditions in which a species can live and survive as a result of environment physic characteristics and the interaction with other species.

Competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective niche of the dominant species completely occupies the fundamental niche of the inferior competitor.

Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use resources -partially or completely-, migrates or get extinguished.

A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the same habitat. This resource partitioning and differentiation in the function of their physic location allows both species to coexist more effectively.

In the present example, both bat species can coexist in the same city but the weaker bat species (species 1) roost at the top of the shorter buildings while dominant species (species 2) roost at the top of the highest buildings.

During the Human Genome Project, scientists created a gene map showing the relative location of each known gene on every human c

Arlecino [84]

Answer:

Approximately 20,500 genes

Explanation:

The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.
