In a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father does not have it (xx), but the mother does (Xx). If they had two children, a son and a daughter, would the  Punnett square show

Assume that levi Fugate was not blue. What was only possible genotype ? why? Zachary fugate and his wife had                % chance of having blue children. Draw a punnett square.  Could Levi Fugate  and his wife have had children with normal genotype (BB) Why and why not ?

A couple who are about to get married learn from studying their family histories that, in both their families, theirunaffected grandparents had siblings with cystic fibrosis(a rare autosomal recessive disease).a. If the couple marries and has a child, what is theprobability that the child will have cystic fibrosis?b. If they have four children, what is the chance that thechildren will have the precise Mendelian ratio of 3:1 fornormal:cystic fibrosis?c. If their first child has cystic fibrosis, what is theprobability that their next three children will be normal?

Suppose two parents, a father with the genotype AaBbccDd and a mother with the genotype aaBbCcDd, want to have children. Assume the loci are inherited independently of each other. Enter your answers as the most simplified fractions (e.g. 1/8 instead of 2/16). What proportion of the offspring are expected to have: The same genotype as the father?  The same phenotype as the father?  All dominant phenotypes?  All recessive phenotypes?

Assuming brown eyes (B) are dominant over blue eyes (b), determine the genotypes of all the following individuals. The blue-eyed son of two brown-eyed parents marries a brown-eyed woman whose mother was brown eyed and whose father was blue eyed. Their child is blue eyed.

Pea plants have pods that are smooth (inflated) or constricted in shape and green or yellow incolor. These two autosomal traits observe the laws of Mendelian inheritance and assortindependently of one another. One gene affects pod shape and one gene affects pod color. Theallele for the smooth shape of pods (I) is dominant over the allele for the constricted shape ofpods (i) and the allele for the green color of pods (G) is dominant over the allele for the yellowcolor of pods (g).A pure breeding female parental pea plant with smooth green pods is cross-fertilized with a purebreeding parental male pea plant with constricted yellow pods. The resulting F1 generationplants are then self-fertilized and F2 generation progeny are obtained.The distribution of the appearance or phenotypes of the pods of the F2 generation plants are______.a- 100% smooth green podsb- 100% constricted yellow podsc- 50% smooth green pods, 50% constricted yellow pods, 0% smooth yellow pods, 0%constricted green podsd-…

Mendel’s observation that two different traits could be inherited independently of each other can be explained by understanding that: During meiosis, the process of chromosome assortment into daughter cells is random Alleles of the genes reside on homologous chromosomes All of the listed choices are correct During meiosis, maternal and paternal members of homologous chromosomes are distributed separately into daughter cells

A light-haired man has blood type O, his wife has dark hair and blood type AB, but her father had light hair. Assume dark hair (H) is dominant to light (h).    What is the probability they will have a child with dark hair and blood type A?   What is the probability they will have a child with light hair and blood type B?   What is the total number of phenotypes their children could show?

Hemophilia is a disease caused by a recessive allele (h), which is found on the X chromosome, non-hemophilia is (H).  A normal man marries a woman that is heterozygous for the trait.  Give the genotypes and phenotypes of all possible offspring?

The shape of a heliodor is an X-linked trait. Male heliodors inherit two X chromosomes, while the females inherit an X and a Y chromosome. The recessive allele codes for the common bell-shape  while the dominant phenotype is a round shape . Hudson is a round male and has offspring with Heidi, a bell-shaped female. They already have one daughter, Hannah, who is shaped like her mother. There is [blank] % that their next child will also be bell-shaped female like Hannah.
