Hi Answer:
13.Sickle cell anemia is an example of what kind of genetic disorder?
Answer: Option C. [Autosomal recessive] [means the gene is present on the autosomes and male and females are equally affected and the recessive means the two copies of genes is necessary for expression in which one from father and another from mother. The person who has only one recessive gene known as a carrier of the disease.]
14.If a female were to inherit a genetic disorder from parents who were healthy, what kind of disorder is likely to be?
Answer: Option B [X-liked recessive] [ Is the type of genetic expression in which mother is a carrier of the trait and it expressed in her son, in this case, daughters become carriers and this effects more males than females.]
15.Huntington disease is an autosomal dominant disorder. What is the probability that a child of heterozygous parent with Huntington disease and a normal parent will have the disease?
Answer: Option D. [75%]when a heterozygous parent (hh)and a parent with huntigons disease (Hh) mate they produce 2 possible genotype i.e. (Hh, Hh, Hh, hh) in which 75% have Huntington disease and 25% are normal].
16. If a person homozygous for an autosomal recessive disorder and a healthy person have children, what is the like hood that the children will have the disorder.
Answer: Option C. [50%]
17.A trait is seen with equal frequency in males and females. Two people who do NOT have the trait might have offspring who do have the trait, at a frequency of approximately 1 in 4. The inheritance of this trait is……
Answer: Option B [recessive and autosomal]
18. A human embryo with 69 chromosomes would
Answer: Option D [ both A and B][it is a case of polyploidy and may be die in mother womb or shortly after birth.]
19.A situation where an organism has multiple copies of its genome is known as
Answer: Option C .[polyploidy]
20.Which of the following can result in aneuploidy?
Answer: Option A [A normal sperm cell fertilize an egg cell in which non disjunction of chromosome 21 occurring during anaphase II] [in aneuploidy conditions the number of chromosomes is either increased or decreased from its actual number. ]
