The most common form of hemophilia is a defect in blood clotting factor VIII, which is caused by a mutant form of a gene on the

X chromosome. Boys who inherit that mutation from their mother suffer from uncontrolled bleeding. Girls carrying one copy of this mutation have near normal blood clotting. Uncommonly, a girl is born with hemophilia even though both parents have normal phenotypes. Which of the statements might explain hemophilia in a girl born to parents with normal blood clotting phenotypes?

Answer:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom, she is XO.

Explanation:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.  

It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.

However, such mutant (X) communicates and expresses itself and she is hemophilic.

This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.

A plant from F1 generation of problem 3 is crossed with a plant from a true breeding dwarf lineage. What are the hw o types and
weqwewe [10]

Answer:

Tt, Tt, tt, tt.

Phenotype: two tall and two dwarfs

Explanation:

The F1 generation will be the crossing of True tall and true dwarf plants to give all tall plants. Kindly note that the genotype for true tall plants is represented by TT, and the genotype for true dwarf plants is represented by tt. The crossing of the two true tall and true short gives Tt, Tt, Tt, Tt; in which the phenotype = all the plants are tall.

If the F1 generation is crossed with the true dwarf plants that is; Tt with tt. It gives us:

T t                          t t.

Tt, Tt, tt, tt. So, the phenotype is two tall and two dwarfs and the genotype is 2 of Tt and 2 of tt.
