4) In tomatoes, round shape (R) is dominant to pear shape (r). A student crossed a plant that had round tomatoes with a plant that had pear-shaped tomatoes and obtained the data below. What are the genotypes of the plants that were crossed. Briefly explain your answer. Phenotype Number of Offspring Round tomatoes 36 Pear-shaped tomatoes 34

1. A pure line Brown coat goat is crossed with pure line White coat goat. Consider the Brown coat is dominant over white coat. a. What is the result (F1) of this cross? b. What is the result when 2 F1 hybrid from (a) is crossed? Give the phenotype, genotype and their ratio. Make sure the phenotype and genotype were aligned with its ratio.

Write the cross using correct symbols. What kind of cross is this called?

1. You are given a female F1 of unknown genotype. You cross the female fly to a homozygous male that has forked bristles and malformed eyes. The offspring of the cross is shown below: (Define symbols for your traits) Phenotype Forked bristles, normal eyes 752 Number Genotype Forked bristles, malformed 56 eyes Malformed eyes, normal bristles Normal eyes, normal bristles 820 64 a. What are the genotypes of the offspring? b. Based on the progeny, what were the genotypes of the F1 parents? What is the distance between for and mal?

Using the following information perform following crosses using the forked line and predict all possible phenotypes types of the offspring. List the number and description of the phenotypes of the offspring. 1. aa BB Cc Dd Ee X aa bb Cc Dd EE 2. Ff Rr Gg dd Bb X Ff RR Gg Dd Bb 3. Dd gg JJ bb Hh Ee X DD GG Jj Bb Hh Ee

Three linked loci are evaluated to determine the recombination frequency of the loci. To set up the test cross, an individual that is true breeding dominant for all three phenotypes is crossed with an individual that is true breeding recessive for all three phenotypes. F1 offspring are crossed with individuals that are recessive for all phenotypes. The phenotypic results are shown in the table below.   Phenotype Number of Offspring Dominant 1, Dominant 2, Dominant 3 322 Dominant 1, Dominant 2, Recessive 3 82 Recessive 1, Dominant 2, Recessive 3 5 Dominant 1, Recessive 2, Dominant 3 2 Recessive 1, Dominant 2, Dominant 3 28 Recessive 1, Recessive 2, Dominant 3 89 Recessive 1, Recessive 2, Recessive 3 312 Dominant 1, Recessive 2, Recessive 3 25   1. Which two phenotypes are parental? 2. What is the map distance between locus 1 and locus 2? 3. What is the map distance between locus 1 and locus 3? 4. What is the map distance between…

The images attached show a parental cross that is homozygous wild female x white male. F1 were intercrossed to produce the F2 generation as indicated below: Wild Female: 416 Wild Male: 192 White Female: 0 White Male: 192 A chi-square analysis was done and an image was also attached. Please discus what conclusions can be made based on the data/findings. What inheritance pattern is this?
