Answer #1

How many different phenotypes can be expressed in a character controlled solely by a one-gene, two-allele system, in which the alleles are codominant?

Answer:-If only one allele is dominant then two phenotypes can be expressed in a character.In two allele system in which alleles are codominant three phenotypes can be expressed in a character controllled solely by a one gene.In three allele system six phenotypes can be expressed in a character.

Example:-Two allele system

first phenotype-DD

Second phenotype-DD'

Third phenotype-D'D'

1. Wool color in sheep is under the control of an autosomal gene which segregates two alleles: B,confers white wool, while the recessive allele b specifies black wool. A population of sheep under Hardy-Weinberg equilibrium was observed: Of 325 individuals, 194 have white wool and 131 have black wool. . What is the frequency of the B allele? b. How many of the 194 white sheep are expected to be heterozygous? 2. Cat coat color is controlled by an X-linked...

Suppose that the leaf color of a certain plant is controlled by one gene locus with two alleles. At this locus the G allele is associated with orange color and is dominant to the g allele, which is associated with green color. You have a plant with orange leaves, but do not know whether that plant's genotype is GG or Gg. Which of the following would help you determine the plant's genotype? Cross two true-breeding, orange-leaved plants to each other...

In diploid organisms, having two homologues of each chromosome can be beneficial if one allele of a gene encodes a nonfunctional protein. Can haploid organisms survive having nonfunctional alleles? Explain your answer.

Recitation 5 short-answer assignment You are investigating two traits in fruit flies controlled by one gene each. The b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). After crossing rugose black flies with smooth brown flies, you obtain an F1 generation of 100% smooth black flies. What are the dominant alleles? (1 pt) What are the genotypes of the two parent flies to perform a dihybrid test cross? (1...

Within a population of butterflies, wing color can be brown or yellow. One gene with two alleles, dominant brown (B) or recessive yellow (b). In this population, 40% (0.40) of all butterflies are yellow. Given this information, determine the allele frequencies for both the B and b alleles. Show all of your calculations clearly.

Explain the principle of “differential gene expression” and how different genes are expressed in different cell types. Describe in detail the two main mechanisms of the transcriptional regulation of gene expression. If you were going to “design” a transcription factor with an unlimited number of protein domains, how would you design this transcription factor so that it could take care of all of the transciptional regulation/expression of the muscle gene myoD.

Assume that plant height and flower size in Four O'Clock plants display antogonistic phenotypes. Four O'Clock plants can be tall or short and the flowers can be large or small. Assume each trait is governed by alleles of a single gene and that each follows Mendel’s first and second laws. You start with two pure breeding strains, one that is tall with large flowers and a second that is short with small flowers. You cross these two strains to each...
