**Question:** How are mitochondrial genes typically inherited?- ○ An individual inherits their mitochondrial DNA from their father.- ○ An individual inherits one copy of mitochondrial DNA from each parent.- ○ An individual inherits their mitochondrial DNA from their mother.- ○ An individual randomly inherits their mitochondrial DNA from either parent. **Understanding Coat Color Genetics in Rabbits**In rabbits, an allelic series determines coat color. The alleles are:- **C** (full color)- **Cch** (chinchilla, gray color)- **Ch** (Himalayan, white with black extremities)- **c** (albino, all white)The dominance hierarchy is: **C > Cch > Ch > c**. This means:- **C** is dominant over all others.- **Cch** is dominant over **Ch** and **c**.- **Ch** is dominant over **c**.- **c** is recessive to all other alleles.When rabbits are crossed as shown in the table, the offspring display the following coat colors:| Cross | Parents | Offspring ||-------|---------------------------|-----------------------------------|| A | full color × albino | 50% full color, 50% albino || B | Himalayan × albino | 50% Himalayan, 50% albino || C | full color × albino | 50% full color, 50% chinchilla || D | full color × Himalayan | 50% full color, 25% Himalayan, 25% albino || E | full color × full color | 75% full color, 25% albino |**Genotype Matching Exercise:**Match the parental genotypes to the appropriate cross:| Cross | Genotype ||-------|-----------------------------|| A | Cc × cc || B | Chc × cc || C | Ccch × cc || D | Cc × Chc || E | Cc × Cc |**Answer Bank Options:**- Cch × cc - Cc × chc - CC × cc - Chc × cc -

Sickle cell anemia is caused by an individual carrying two recessive copies of the hemoglobin gene (hemoglobin gene is labeled Hb, and the recessive version is Hbs). Thus, to have sickle cell anemia, a person must have the genotype HbSHbS. A person that is HbAHbA carries two copies of the normal hemoglobin gene and does not have sickle cell anemia. A person that is heterozygous (HbAHbS) produces enough normal hemoglobin to not have sickle cell anemia but is also resistant to malaria. People that are heterozygous are called “carriers” because they carry the recessive allele but do not express the recessive phenotype. a. A couple are both resistant to malaria but do not have sickle cell anemia. Draw a Punnett square to represent this cross. b. What is the probability that the couple has three children where one child does not have a recessive allele, one child is resistant to malaria and does not have sickle cell anemia, and one child has sickle cell anemia?
Sickle Cell Anemia is caused by an abnormal form of haemoglobin, the part of the red blood cell that carries oxygen around the body. The red blood cells become stiff and block blood vessels, causing pain and damage and quickly destroying blood cells, leading to anemia. It is estimated that approximately 1 in 32 000 people in Canada are affected with sickle cell anemia.The disorder occurs when a person inherits two recessive genes for the condition. What are the frequencies of the recessive disease allele and the dominant normal allele in the population's gene pool? Select one: a. Recessive Allele Dominant Allele 0.559% 99.4% b. Recessive Allele Dominant Allele 5.59% 94.4% c. Recessive Allele Dominant Allele 0.313% 99.7% d. Recessive Allele Dominant Allele 0.00313% 99.9%
In humans, a dimple in the chin is a dominant characteristic controlled by a single gene. A man who does not have a chin dimple has children with a woman with a chin dimple whose mother lacked the dimple. What proportion of their children would be expected to have a chin dimple? A man with a chin dimple and a woman who lacks the dimple produce a child who lacks a dimple. What is the man’s genotype? A man with a chin dimple and a non-dimpled woman produce eight children, all having the chin dimple. Can you be certain of the man’s genotype? Why or why not? What genotype is more likely, and why?
Cystic fibrosis in humans is caused by mutations in a single gene and is inherited as an autosomal (non-sex chromosome) recessive trait. An unaffected couple has two children. The first child has cystic fibrosis, and the second child is unaffected. What is the probability that the second child is a carrier (heterozygous) for the mutation that causes the disease? 2/3 1 1/2 3/4
What is the Characteristic pedigree for mitochondrial disease?
In humans, the gene for albinism (a) is recessive to the gene for normal skin pigmentation (A). If two heterozygous persons have children, what is the probability they will have a child who is an albino? What is the probability they will have a child that is a carrier of the recessive gene?
Niemann Pick Type C disease is a recessive disorder that causes the accumulation of cholesterol and other lipids in lysosomes, ultimately affecting both the liver and the nervous system. Below are the genotypes and phenotypes of offspring of a family with a history of Niemann Pick. 7 NN ( all normal phenotype) 3 Nn (all normal phenotype) 4 nn (1 early onset dementia, 1 mid-life onset dementia, 2 late-onset dementia). From this information, Niemann-Pick disease is an example of: A) variable expressivity B) incomplete dominance C) incomplete penetrance D) variable expressivity and incomplete penetrance E) multiple alleles
When two mutant flies having white eyes were crossed, all of the offspring showed wild type red eyes. How is this possible? The parents carried mutations on different but complementary genes whose products are both required for the red eye phenotype. The parents carried different mutations on the same gene whose product is required for the red eye phenotype. The parents carry recessive lethal mutations that affect the survival of the white-eyed flies among the offspring. The red eye phenotype is recessive to the white eye phenotype, which is why the red eye only appears in the F1 generation. The white eye allele shows dominant epistasis over the red eye allele.
