- A researcher studied six independently assorting genes in a plant. Each gene has a dominant and a recessive allele: R black stem, r red stem; D tall plant, d dwarf plant; C full pods, c constricted pods; O round fruit, o oval fruit; H hairless leaves, h hairy leaves; W purple flower, w white flower From the cross (P1) RrDdccOoHhWw x (P2) RrddCcooHhww, determine: Note: RrDdccOoHhWw is one genotype. a. How many kinds of gametes can be formed by P1?b. How many genotypes are possible among the progeny of this cross?c. How many phenotypes are possible among the progeny?d. What is the probability of obtaining the RrDdccOohhww genotype in the progeny?e.

O BBRR BBRr BBrr BBRR BbRr O bbRR O bbRr O bbrr O Black O White O Rough OSmooth O Rough O SmoothStar eye A peculiar eye condition known as "star” is manifested as a dominant gene in Drosophila. Its recessive allele R* produces the normal eye of wild type. The expression of R can be suppressed by the dominant allele of another locus, Ru-R. Ru-R*, as the recessive allele of the said locus, has no inhibitory effect on R*. When a normal-eyed male of genotype Ru-R Ru-R RR is crossed to a homozygous wild-type female of genotype Ru-R* Ru-R* R*R*, what phenotypic ratio is expected in the F2?
- In humans, tongue rolling (R) is completely dominant to the inability to roll the tongue (r), unattached earlobes (E) are completely dominant to attached earlobes (e), • presence of dimples (D) is completely dominant to the absence of dimples (d), • and a peaked hairline (H) is completely dominant to a straight hairline (h). A woman of genotype rr Ee DD Hh and a man of genotype Rr Ee Dd hh are planning to have a child. What is the probability that: i. The child will show the recessive trait for all four characteristics? 11. The child will look like its mother for all four characteristics? The the child will not look like its father for all four characteristics? 111.F1 female Drosophila heterozygous for cinnabar eye (cn), vestigial wings (vg) and roof wings (rf) genes were test crossed with males homozygous for all three traits.

Autism is a neurological disorder thought to becaused by mutant alleles of one or more genes.Scientists had been wondering why the number ofchildren diagnosed as autistic increased dramaticallyin a decade, from 1 in 500 in 2002 to 1 in 88 in 2012.Researchers now think that they might have found atleast part of the answer: Men are fathering children atlater and later ages. A paper published in the journalNature in 2012 showed a correlation between paternalage and the incidence of autism; the age of the motherwas not a factor. How does this observation provide apossible explanation for the apparent increase in therate of autism?
- This is a conjectural question— there is no single “right” answer— that is good for discussion over tea and crumpets. In what ways might it be possible to prevent genetic discrimination due to information made available by the Human Genome Project?Hello! I have a question. Question: “Match” each example under the correct type of dominance. (For matching I’ll list the numbers, and you can put the number with the correct type of dominance) 1. red rose + white rose= pink rose 2. white mouse + brown mouse = Brown and white dots 3. brown eyes + green eyes= brown eyes 4. straight hair + curly hair = wavy hair 5. dimples + no dimples = no dimples 6. green pea plant + yellow pea plant = yellow pea plant 7. red rose + white rose= red rose with white stripes Types of dominances: Complete dominance (Mendellian) Incomplete dominance Co-dominanceI'm having trouble with my genetics study guide, and am stuck on this question. If someone could explain it with the work it would help me so much. Thank you! In humans, the inheritance of the ABO blood group system exhibits both complete dominance (alleles IA and IB are dominant to allele i) and codominance (alleles IA and IB). In addition, thalassemia shows incomplete dominance; heterozygotes (Tt) exhibit a mild form of the disease (thalassemia minor) and homozygotes (tt) have a more severe form (thalassemia major). A man has blood type A and his mother has blood type O. His wife has blood type AB. Both members of the couple have thalassemia minor. What is the probability that they will have a child with: a. thalassemia minor and blood type A? b. no anemia and blood type AB? c. thalassemia major and blood type B?
