A male mouse is genotypically e+/e-, where e (ebony) is an
autosomal gene. Of the 4 gametes produced by single a meiosis, how
many of them will carry booth e- allele and the X chromosome
?
a)None
B) 1/4
C) 2/4
D) either none or 1/4
E) Either none or 2/4
Homework Answers
1/4 of the them will carry both e- allele and the x chromosome.
Possible combinations are e -ve and x , e-ve and y , e +ve and x and finally e+ve and y.

4. The Hardy-Weinberg Proof. Consider a gene that has only two alleles R (dominant) and r (recessive). The sum total of all R plus all r alleles equals all the alleles at this gene locus, or 100% of all the alleles for that gene. Let p = the percentage or probability of all R alleles in the population. Let q = the percentage or probability of all r alleles in the population. If all R + all r alleles =...

1) Coat color in mice is determined by several independently assorting autosomal genes. Gene A is involved in the distribution of pigment along the hair. A dominant allele (A) produces a hair color called "agouti"--the hair has dark pigment at the base and tip of each hair shaft and yellow pigment in the central portion of the shaft. Homozygous recessive mice (aa) are missing the yellow stripe and thus have solid dark-colored hair. Gene B is involved in the color...

Question 1. Consider 3 gene loci in the pea plant. Locus 1 affects seed color; allele G for green, g for yellow. Locus 2 affects seed shape; allele R for round, r for wrinkled. Locus 3 affects flower color; allele B for red, b for white. Each uppercase allele is completely dominant to their corresponding lowercase, recessive allele. Each locus is on a different non-homologous chromosome; so, the loci segregate or sort independently from each other during meiosis. Two parent...
