Answer: - Predict an unknown genotype of a purebred dominant plant.
Explanation:
The genetic make up of the organism is called as the genotype. It describes the form of genes or allelic forms present in the organism. A test cross is used to determine the genotype of the organism. In this cross the organism with the unknown genotype is done with that of the organism with the known genotype. It also determines the fact that the organism is either homozygous dominant or hetrozygous.
On the basis of the above description, Predict an unknown genotype of a purebred dominant plant.
Kidney. The kidney plays the role of keeping blood pressure in check by altering the blood volume.
Alcohol acts as a diuretic because it inhibits the release of ADH.
Answer:
Let's consider that the allele 'B' is for Black hair colour and it is dominant. Let's consider that the allele for red hair colour is b.
Let's consider the allele for lacking horns or polles is 'P' and it is dominant. The allele for having horns is 'p' and it is recessive.
When two heterozygous black, lacking horns (BbPp) are crossed, the results will have the probability of 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned organisms.
