Incomplete dominance and epistasis are both terms thatdefine genetic relationships. What is the most basicdistinction between these terms?
What is the difference in meaning between the terms geneticrecombination and crossing over?
In the fruit fly, recessive mutations in either of two independently assorting genes, brown and purple, prevent the synthesis of red pigment in the eyes. Thus, homozygotes for either of these mutations have brownish-purple eyes. However, heterozygotes for both of these mutations have dark red, that is, wild-type eyes. If such double heterozygotes are intercrossed, what kinds of progeny will be produced, and in what proportions?

- Individuals of genotype AaBb were mated to individuals of genotype aabb. One thousand offspring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is it? Are these loci linked? What are the two parental classes and the two recombinant classes of offspring? What is the percentage of recombination between these two loci? How many map units apart are they?arrow_forwardHuman sex chromosomes are XX for females and XY for males. a. With respect to an X-linked gene, how many different types of gametes can a male produce? b. If a female is homozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele? c. If a female is heterozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele?arrow_forwardL, R, P and D are four genes located on the same chromosome in a diploid organism. Map distances between different pairs of genes were determined and the following results obtained. Based on these data, what is the order of the genes on the chromosome? D-R: 35 CM P-D: 5 CM L-R: 10 CM D-P: 30 CM D-L 25 CM P-R: 40 CM Note that only one orientation of the order is given as an answer choice. For example: ABCD has the same order as DCBA, but only ABCD would be listed as a possible answer. So be sure to check both orientations when comparing your gene order to the possible answer choices.

Supposing two strains of autotetraploid plants are available and their genotypes are as follows: GGgg – in this plant the gene is close to the centromere Gggg – in this plant the gene is far from the centromere If these two plants are crossed: a) provide the gametes that can be obtained from the two plants; b) provide the genotypic and phenotypic ratios of the offspring.arrow_forwardIn Drosophila,, the curled mutation (cu, chromosome 3, position 50.0) results in wings that curl up, while ebony (e, chromosome 3, position 70.7) results in a dark body.

- A standard three-point mapping is conducted for recessive mutations in autosomal genes purple eye (pr), curved wing ( c) and black body (b). Their wild type alleles are also used for genetic mapping. An F1 Drosophila female heterozygous for purple eye (pr), curved wing (c) and black (b) is crossed to a triply homozygous mutant male. The observed numbers and phenotypes of the offspring are as follows: 360 pr c b 380 pr+ c+ b+ 104 pr c+ b 96 pr+ c b+ 30 pr c b+ 20 pr+ c+ b 6 pr c+ b+ 4 pr+ c b PROVIDE THE FOLLOWING: A) State the order of genes on this chromosome.
