Tju [1.3M]

Answer:

All the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

Explanation:

Given

Tallness ( T) is dominant to dwarfness (t)

Red (R) flower color is dominant to white (r)

It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance

Genotype of dwarf red snapdragon is RRtt

Genotype of a plant homozygous for tallness and white flowers is rrTT

The punnet square representing the cross between RRtt and rrTT is as given below-

Rt Rt Rt Rt

rT RrTt RrTt RrTt RrTt

Thus all the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

Who devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations?.

Dominik [7]

Landsteiner Bertillon devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations.

<h3>What about blood group?</h3>

According to the presence or absence of antibodies and hereditary antigenic compounds on the surface of red blood cells, blood is classified according to its type.
Depending on the blood group system, these antigens could be proteins, carbohydrates, glycoproteins, or glycolipids.
The genes that a person got from their parents determine what blood type they have.
There are numerous systems for classifying blood types, but ABO is the most popular one.
The ABO group is divided into four main categories: A, B, O, and AB.
There are eight more blood types within these groupings.
Each of the eight blood types has a particular ability to save lives.
The majority of people (37% of the population) have the blood type O+, which is the most prevalent. This indicates that there is a greater need for this blood type for blood transfusions.
