Assume that having a dimple in your chin is a recessive trait, and can be labeled dd. Find the probability that the offspring of dad Dd, and mom Dd will have a child who has a dimpled chin. Show your work.
P( offspring of dad Dd, and mom Dd will have a child who has a dimpled chin)=P(dd trait from parents)
=P(d trail from Father and d trait from mother )=P(d trait from mother)*P(d trail from father)=(1/2)*(1/2) =1/4

1)Dimples is a dominant trait and represented as “D”. No Dimples is a recessive trait and represented as “d”. The dimples/no dimples alleles follow Mendelian genetics. What is the genotype of an individual who is heterozygous for the dimples trait? Dd DD dd Dimples No dimples 2) Dimples is a dominant trait and represented as “D”. No Dimples is a recessive trait and represented as “d”. The dimples/no dimples alleles follow Mendelian genetics. Person A has dimples and is homozygous...
1. A dimpled woman wants to have children and finds a suitable donor at her local sperm bank. Her genotype is Dd, and her chosen sperm donor’s genotype is dd. Her plan is to produce 3 children, and she is curious to know the probability that she will have at least two children with dimples. That probability is: 2. A dimpled woman wants to have children and finds a suitable donor at her local sperm bank. Her genotype is Dd,...
The red-green color vision deficiency gene, a recessive trait, is on the X chromosome. Now, A male with normal vision and a female whose father could not see red or green are mated; What is the probability that the child will not see red or green, if its a boy? what if it's a girl? Explain your answer. what I think is that as the female's father gave her X chromosome and a female has XX chromosome (one active and...
1. In the P generation, whena homozygous dominant trait is crossed with a homozygous recessive trait, all the Figeneration will show the dominant trait. What will be the genotype and phenotype ratio in the F2 generation when the Fi generation is crossed? 2 In humans, brown eyes (B) are dominant over blue (b). A brown-eyed man marries a blue-eyed woman and they have three children; two of the children have brown eyes and one has blue eyes. Draw the Punnett...
Hemophilia B is an X-linked recessive trait that causes problems with blood-clotting. (2 pts) If a normal man and a woman who is a carrier for hemophila decide to have children, what is the probability their first child will have hemophila? Please show your work using a Punnett Square. (3 pts) How would X inactivation in the woman described above (a carrier for hemophilia) affect her phenotype for hemophilia symptoms?
A human disease known as cystic fibrosis is inherited as a recessive trait. For example, the possible outcomes of a child inheriting cystic fibrosis genes are CC Cc cC cc if the child’s parents had one copy of each version of the gene so the probability of having a disease is ¼. Find the probability that 3 out of 6 children of these parents will have a cystic fibrosis.
Achondroplasia is a dominant condition that leads to dwarfism. Hereditary deafness is a recessive trait. John, who is achondroplastic and hears normally, marries Ann, who has normal height and hearing, but whose father was deaf. They have a non-achondroplastic 3 year old son who is deaf. Draw the pedigree for this family, indicating all the known family members. Give the genotypes of John, Ann, and their son. If John and Ann have another child, what is the probability that The...
Hemophilia in humans is a recessive sex-linked trait. A man with hemophilia and a woman who does not have hemophilia have a daughter who does not have hemophilia. She then marries a man who does not have hemophilia. What is the probability that their first child will be a daughter with hemophilia? A daughter without hemophilia? A son with hemophilia? A son without hemophilia? If the couple has four sons, what is the probability that all four will be born...
What is the probability of two offspring in a row having
mid-digital hair and freckles?
Unit C: Assignment Module : Mendelian Genetics and Inheritance Use the following information to answer questions 11 and 12. Use the following into Mid-Digital Hair and Freckles Finger mid-digital hair (M) is dominant over the recessive trait of no mid-digital hair (m). Freckles are dominant over the recessive trait of no freckles . It is important to note that this example of mid-digital hair and...
1. The human gene for blue eyes (b) is recessive to brown eyes (B) and is inherited as a simple recessive trait. Two brown eyed parents have five children, four brown eyed and one blue eyed. Determine the genotype of the parents and explain the proportion of offspring by linking phenotype with possible genotypes. 2. Haemophilia is an X linked recessive trait (h). Suppose a young lady comes to you for advice in your capacity as a marriage counsellor. She...
