Answer 10
Correct option is E. Three or more alleles for a genetic loci
Reason: This is not required as two alleles per loci can be there for a 3-point mapping. Requirement is of 3 genes not of three alleles for a gene.
Answer 11
Correct option is D. Complete linkage
Reason: The progeny shows very high frequency of parental types. So, the genes in question are completely linked.
Which of the following is not necessary for a 3-point mapping experiment? One parent must be...

A cross is made between a pea plant with round, yellow seeds (WwGg) and one with wrinkled, green seeds (wwgg). The progeny that resulted had the following traits: round, green: 82 round, yellow: 18 wrinkled, green: 10 wrinkled, yellow: 90 1. Which alleles were on which chromosome in the doubly heterozygous parent? 2. What is the distance in cM between these two genes?
In this tutorial you will examine dihybrid crosses: crosses
where alleles at separate loci assort independently into gametes at
meiosis. You will also use logic to determine unknown genotypes,
phenotypes, and genetic ratios from given data.
Part A - Deducing phenotypes and genotypes of selfed parents
Mendel studied pea plants dihybrid for seed shape (round versus
wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele
(r) and
the yellow allele...

1.Certain characteristics, like coat color in many animals, is influenced by multiple genes. The phenomenon during which the presence of a homozygous recessive genotype at one locus "overrides" or masks the phenotype that would otherwise be produced by the alleles at another locus (regardless of whether they are dominant or recessive) is called: pleiotropy codominance Punnett effect recessive Epistasis 2. Which of the following would be considered a pleiotropic gene? A gene that-along with several others-influences a single phenotype, such...
QUESTION 3 A test cross is set up to establish the genotype of a plant with rounded peas. It is crossed with a plant that is homozygous for wrinkled peas. A round pea shape is dominant over the wrinkled shape. The offspring derived in the test cross exhibit a 50:50 ratio of wrinkled and round peas. What is the genotype of the parent in question? Homozygous for round pea shape. Heterozygous for pea shape. Homozygous for wrinkled pea shape. Heterozygous...

This tutorial will take you step by step through the question. In cucumbers, dull fruit (D) is dominant to glossy fruit (d), and orange fruit (R) is dominant to cream-colored fruit (r). The gene that codes for dull versus glossy assorts independently from the gene that codes for orange versus cream-colored. A plant that has dull and orange fruits is crossed...

E)incomplete dominants. 2) Mendel carried out most of his research with A)livestock -B)pea plants. C)guinea pigs. D)fruit flies. E)bacteria. 3) Which of the following is true according to Mendel's law of segregation? A)Each individual contains two alleles for each trait. B)Fertilization restores the presence of two alleles. C)Alleles separate from each other during gamete formation. D)Each gamete contains one copy of each...
Please help me to answer these questions, thank you! 1-When Mendel crossed a plant with smooth green peas and a plant with wrinkled yellow peas, what did he find? a- Color and shape of pea are linked (if you have a smooth pea it has to be green) b- Color and shape of pea are not linked (if you have a smooth pea, it can be green or yellow) c- Only yellow peas produce leaves d- Only smooth peas produce...
