Write the possible genotypes Mendel got, when he crossed F₁ tall pea plant with a dwarf pea plant.

Why is a plant with genotype Tt referred to as heterozygous'?

Why in a test cross, did Mendel cross a tall pea plant with a dwarf pea plant only?

What will be the percentage of gametes ry , formed by an individual with genotype RrYy ?

What will be the karyotype of an individual who has developed from the zygote formed by an XX egg fertilized by a Y sperm ?Name the abnormality with which he will be suffering from .

Show through a cross all the possibility of the genotypes of the progeny when a man with blood group B marries a women with blood group A, both heterozygous for the trait.

What is the probability of Haemophilia in the son when a normal homozygous women is married to a Haemophilic man?

Justify the situation that in human beings, sex of the child is determined by father, and not by mother?

In sexually reproducing organisms what is the contribution of the parents to their offspring \(\frac{1}{2} \) of their genes or \(\frac{1}{4}\) of their genes

A) Draw a pedigree chart of a family consisting of the following members, age given Within brackets: - father [70] is normal, mother [65] is a carrier, one son [40] is Normal, second son [37] is affected (sufferer). One daughter (33) is normal (non - Carrier), second daughter (30) is normal (carrier).
b) If no daughter in the above family could be born as affected for this trait , work out in a punnet square to find out if this trait could be phenylketonuria and conclude by saying yes or no . [You can use the letters ‘A’ and ‘a’ for the dominant and recessive allele of this gene respectively]

What is the name given to the genes present in the different region [Non-Homologous] of the ‘Y’ chromosomes and what they code for?

Turner's syndrome is a sterile female generally with normal intelligence and known viable monosony in humans. Is the combination '44+YO' is also viable. Justify?

Name a cross whose progenies can easily be analyzed to predict the genotype of the organism under observation?

Which law of inheritance of Mendel is universally acceptable and without any exception? State the law.

Name and state the law of Mendel, which explains the expression of only one of the parental characters in the F₁ generation of a monohybrid cross.

What is the proof for or what indicates that the characters Mendel studied did not show blending?

Do you think Mendel's law of inheritance would have been different if the characters he chose were located on the same chromosome? Why?

When a tall pea plant was self-pollinated, one-fourth of the progency were dwarf.  Give the genotype of the parent and the dwarf progenies.

Why do certain genes tend to be inherited together in a cell at the time of cell division?

In a test cross progeny of pea plats, all were bearing violet flowers. Give the genotypes of the parent pea plants.
