Genetics Problems. Show your crosses. It must contain: (a) parental genes, (b) genotypic ratio, (c) phenotypic ratio, (d) hybrid cross and (e) other answer needed in the question. A. Cock-feathering in chickens is a trait limited to expression only in males and is determined by the autosomal recessive genotype hh. The dominant allele H produces henfeathered males. All females are hen-feathered regardless of genotype. A cock-feathered male is mated to a female. Show the cross.
D) Genetics Problem show the table and word In certain breeds of chickens, the allele "B" is responsible for black feathers whereas the contrasting allele "b" produces feathers that are white. Another r pair of alleles influences the shape of the feathers. "F" produces straight feathers whereas the contrasting gene for "f results in the frizzled condition. Give the genotypic and phenotypic ratios to be expected from the following cross: white, frizzled hen with a heterozygous black, homozygous straight rooster. Genotypic Ratio: Phenotypic Ratio:

no need to explain just need n=to know if it a.b.c and d. 1.) In a species of dog, a mutant gene that causes deafness is found on the Y chromosome. What type of offspring will be produced between a cross of male dog whose father is deaf, and female dog whose father is not deaf? a.) 25% normal female dogs, 25 % deaf female dogs, 25 % normal male dogs, 25 % deaf male dogs b.) 50% normal female dogs, 50 % deaf male dogs c.) 50% deaf female dogs, 50 % deaf male dogs d.) 50% normal female dogs, 25 % deaf male dogs, 25% normal male dogs 2.) Mendel crossed true breeding plants that had yellow pods with true breeding plants that had green pods. Yellow pod colour (Y) is dominant over green pod colour (y). Predict the genotypes and phenotypes of F1 generation. a.) yellow pods with genotype yy b.) yellow pods with genotype Yy c.) green pods with genotype Yy d.) green pods with genotype Yy
Genetics Problems. Show your crosses. It must contain: (a) parental genes, (b) genotypic ratio, (c) phenotypic ratio, (d) hybrid cross and (e) other answer needed in the question. A. Let us consider two sex-influenced traits simultaneously, pattern baldness and short index finger, both of which are dominant in men and recessive in women. A heterozygous bald man with long index finger marries a heterozygous long-fingered, bald woman. Determine the phenotypic expectations for their children.
Cat fur coat color genetics is interesting. Orange fur is dominant (''B'') to black fur (''b'') and piebald, which is white spotting, is dominant (''S'') to non-white-spotted (''s''). Both of those genes are located on the X chromosome. In addition, in cats, somatic cells exhibit X-inactivation randomly, which explains why there are tortoiseshell cats (when heterozygous, have orange and black spots) as well as calico cats (orange and black but also with white spots). An orange and white spotted male is mated with a tortoiseshell female. State the genotype of the male and the female.

Keeping it in the family!”- How do you think consanguinity is increasing the risk factors of genetic disorders? Explain with examples (at least two). It won’t be possible to change the tradition all of a sudden. If you are a clinical geneticist, how you will be managing this type of community?
Problem Solving: In Drosophila, the gene that controls red eye color (dominant) versus white eye color is on the X chromosomes. What are the expected phenotypic results if a heterozygous female is crossed with a white-eyed male? In cats, S = short hair; s = long hair; XC = black coat; Xc = yellow coat; XCXc = tortoiseshell (calico) coat. If a long-haired yellow male is crossed with a tortoiseshell female homozygous for short hair, what are the expected phenotypic results?
MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. In humans and other mammals, biological sex is determined by a pair of sex chromosomes: XX in males and XY in females.II. In the sexual pattern of inheritance, an X-linked pattern will be present and can attached both on the X and Y chromosomes. a. The first statement (I) is correct and the second statement (II) is wrong b. The first statement (I) is wrong and the second statement (II) is correct c. Both statements are correct d. Both statements are wrong MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. One important event that happens in Meiosis at Prophase 1 is when crossing over between sister chromatids of non-homologous chromosomes takes place.II. This crossing over is the exchange of genetic material that causes variations among individuals. a. The first statement (I) is correct and the second statement (II) is wrong…
SUBJECT: GENETICS Topic: Probability 1. Consider albinism a trait to occur in a human family. If two parents areheterozygous for such trait, the probability of having a normally pigmented child is 3//4 and having an albino child is ¼. What is the probability that 2 will be normal and 1 will be albino?
mapping gene The genes for ruby eyes (rb), tan body (t) and cut wings (ct) are all found on the X-chromosome of Drosophila melanogaster. All of these are recessive traits. They map in the order rb, ct, t with 12.5 map units between rb and ct and 7.5 map units between ct and t. Suppose you cross a cut wing male with a homozygous female that is both tan and has ruby eyes. What will the F1 females look like? Draw map of the section of the X chromosomes that has these 3 genes for the F1 females Assume you testcross your F1 females. What progeny classes would you expect? ii. Give approximate numbers for each class based on a total of 2000 progeny. Assuming the i=1 and there are no double crossovers. Assuming the i=0 and there are the expected number of double crossovers.
