A white-eyed  (X-linked  recessive character)  female  fruit  fly  is  mated  to  a  red-eyed  male.  One  of their  progeny  is  a white-eyed  female.  What  is  the  most  likely  set  of  chromosomes  of  this  whiteeyed  daughter?  A)  XXY B)  XX C)  XO D)  XXX E)  XYY

Cystic fibrosis (CF) is an autosomal recessive trait. A three-generation pedigree is shown below for a family that carries the mutant allele for cystic fibrosis. Note that carriers are not colored in to allow you to figure out their genotypes.      Normal allele =  F      CF mutant allele =  f        What is the genotype of individual #13? A) ff B) FF C) Ff  D) it is impossible to tell

The image shows a pair of homologous chromosomes from a single parent before gamete production. M1 and M2 are maternal chromosomes, while P1 and P2 are paternal chromosomes. Two traits are shown: D represents seed color (D – green, d – yellow), while F represents flower color (F – purple, f – white). These two traits follow the patterns of basic Mendelian genetics. During crossing-over between the M2 F allele and the P1 f allele, a mutation occurred and the portion of P1 did not reattach to the chromosome. Which of the following explains what would happen to the proportion of white flowers in a population resulting from this mutation? A - There would be an increase in the proportion of white flowers because the f allele is distributed to more gametes. B - There would be a decrease in the proportion of white flowers because the f allele is not distributed to as many gametes. C - There would be an increase in the proportion of white flowers because the f allele would not be masked by the…

32) Which term correctly describes the phenomenon that is taking place when a single gene influences two or more seemingly unrelated phenotypic traits? A) Epistasis B) Pleiotropy C) Multi-allelic D) Polygenetic traits genes

12. A heterozygous black mouse is crossed with a white mouse. a) Which color is dominant? b) How did you know? c) Which letter will stand for the dominant color? d) Which letter will stand for the recessive color? e) What is the genotype of the white mouse? f) What is the genotype of the heterozygous black mouse? g) Complete the Punnett Square below for this cross. h) What percent of the offspring will be black?

1) If the parents of the first generation are SS and ss, then the second generation (mating of first-generation) will be, (choose) a) all Ss b) 1/4 SS, 1/2 Ss, and 1/4 ss c) 1/2 Ss and 1/2 SS d) 1/2 ss and 1/2 Ss 2) In a cross of Tt x Tt, the percentage of offspring that will have the same genotype as the parents is   (choose)  a) 75% b) 25% c) 50% d)100%
