You are attempting to map the chromosome of a silk moth. You know that red eyes and white banded wings are recessive to the wild type eyes and wings. You cross a homozygous recessive moth with a homozygous dominant moth. The f1 generation has all wild type traits. You then allow the f1 progeny to interbreed and acquire the following numbers: Wild type eyes and wild type wings -418 Red eyes and wild type wings -16 Wild eyes and white banded wings- 16 Red eyes and white banded wings - 426 Determine the recombination frequency of Red eyes and white banded genes. Also, determine the distance between them.

Wild type fruit flies have grey bodies and straight wings. Yellow bodies and curly wings are both recessive phenotypes. The body color gene is X-linked; the wild type allele is designated XY+. The wing shape gene is autosomal; the wild type allele is designated C+. You cross a pure breeding yellow-bodied, curly-winged female with a grey-bodied, straight-winged male to produce an F1 generation. Use this information to answer questions X-Y below. 20) You cross two F1 flies to produce an F2 generation. What proportion of the F2 female flies are expected to have curly wings and yellow bodies? a) 1/16 b) 1/4 c) 1/8 d) 3/8 e) 3/16
Just like in fruit flies, pea plants are a famous model organism for genetics. Pea plants can have purple flowers or white flowers. Let's use P to represent the allele for Purple and p to represent the allele for white. In pea plants, purple flowers are fully dominant to white. Imagine a cross between a heterozygous male plant and a female that is homozygous recessive for flower color. What are all the possible gametes that the FEMALE plant could make? O Pp O p dd
In corn plants, a dominant allele (K) allows kernel colour and a recessive allele (k) inhibits kernel colour when homozygous. On a different chromosome, the dominant gene P causes purple kernel colour and the homozygous recessive genotype causes red kernel colour.A true breeding white corn plant was crossed with a purple corn plant, yielding 50% red corn plants and 50% purple corn plants.What are the genotypes of the parental corn plants? Select one: a. KKPp kkpp b. KkPP kkPP c. kkPp KkPp d. KKPP kkPp
In silkmoths (Bombyx mori), red eyes (re) and white-banded wings (wb) are encoded by two mutant alleles that are recessive to those that produce wild-type traits (re+ and wb+); these two genes are on the same chromosome. A moth homozygous for red eyes and white-banded wings is crossed with a moth homozygous for the wild-type traits. The F1 have wild-type eyes and wild-type wings. The F1 are crossed with moths that have red eyes and white-banded wings in a testcross. The progeny of this testcross are wild-type eyes, wild-type wings red eyes, wild-type wings wild-type eyes, white-banded wings red eyes, white-banded wings a. What phenotypic proportions would be expected if the genes for red eyes and for white-banded wings were located on different chromosomes? b. What is the rate of recombination between the gene for red eyes and the gene for white-banded wings?
Two pure-breeding strains of flies are mated, and the F1 are intercrossed. The first strain has curled wings and black bodies. The second strain has straight wings and brown bodies. The F2 progeny are 271 straight wings with brown bodies, 31 curled wings with black bodies, 94 curled wings with brown bodies and 90 straight wings with black bodies. If instead of the above, assume the wing shape gene and the body color gene are completely linked. From parents that are curled winged with brown bodies mated to straight winged with black bodies, what would be the outcome of an F1 intercross? (Specify the phenotypes and the frequency of each expected).
You are doing a genetics experiment with the fruit fly. In the “P” generation, you cross two true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. Assume the genes are not found on a sex chromosome. Indicate the body color alleles with B and b and the wing size alleles with N and n. a) The genotypes of the flies in the P generation are: Female: ______________ Male: ______________ b) The genotype of the flies in the F1 generation is: _____________ c) You now take an F1 female and cross her to a true-breeding black, wingless male. This male’s genotype is: ______________
You are studying 2 traits, fur color and length, in rabbits. You cross a true-breeding brown, short furred rabbit with a true-breeding white, long furred rabbit. The F1 offspring are all white, short furred rabbits. You then cross an F1 offspring to a rabbit homozygous recessive for both traits. Assuming that fur color and fur length are independently assorting, what phenotypic ratio would you expect to see in the F2 generation? white, short: white, long: brown, short: brown, long
Hemophilia and color blindness are both recessive conditions caused by genes on the X chromosome . To calculate the recombination frequency between the two genes, you draw a large number of pedigrees that include grandfathers with both hemophilia and color blindness , their daughters (who presumably have one chromosome with two normal alleles and one chromosome with two mutant alleles), and the daughters’ sons. Analyzing all the pedigrees together shows that 25 grandsons have both color blindness and hemophilia 24 have neither of the traits , 1 has color blindness only and 1 has hemophilia only . how many centimorgans seperate the hemophilia locus from the locus of the color blindness.
A recessive allele causes Drosophila to have white eyes instead of wild-type eyes. This eye colourgene is known to be X-linked. In a cross between homozygous wild-type females and white-eyedmales, all F1 progeny have wild-type eyes. What ratio of wild-type to white-eyed progeny can be expected in each sex if F1 females arecrossed to males of the same genotype as their father?a. Males – 1 : 0; females – 1 : 0b. Males – 1 : 1; females – 1 : 0c. Males – 0 : 1; females – 1 : 1d. Males – 1 : 1; females – 1 : 1

You are trying to determine whether a horn shape (curved = dominant, straight = recessive) in cows is controlled by a sex-linked or autosomal gene. You cross a true-breeding curved female with a true- breeding straight male and all the F1 offspring have curved horns.
