A wild population of pea plants has two alleles for flower color in its gene pool. A dominant allele (P) specifies purple flowers; a recessive allele (p) specifies white flowers. If the die frequency of allele P is 0.75, what is the expected frequency of allele p?
4.) A man and a woman have a child. The father is blood type A, and one of his parents was blood type A and the other was blood type O. The mother is blood type B, and one of her parents was blood type B, the other type O. Both the father and the mother are carriers of the Bombay allele. (Neither of the type-O grandparents were type O because of the Bombay allele – they had the regular type O genotype.) WhataretheoddsthattheirbabywillhavebloodtypeO? WhataretheoddsthattheirbabywillhavebloodtypeAB? (Hint – for this question, you should draw out a pedigree and fill in as much as you can for the genotypes of BOTH genes that are involved.)
3) The ability to curl ones’ tongue up on the sides (T) is dominant to not being able to roll your tongue (t). a. A woman who can roll her tongue marries a man who cannot. The first child has the same phenotype as the father, what are the genotypes of the mother, father, and this child? b. What is the probability that the second child won’t be able to roll it’s tongue?
2) A researcher crossed a heterozygous yellow seed plant (Yy) and a recessive green seedplant (yy). Draw a Punnett Square and determine the genotype and phenotype ratios ofthe offspring.
In sweet pea plants, an allele for purple flowers. (P) is dominanl when paired with a recessive allele for red flowers (p). An allele for Jang pollen grains (L) is dominant when paired with a recessive allele for round pollen grains (L). Bateson and Punnett crossed a plant having purple flowers and long pollen grains with one having white flowers and round pollen grains. All F1 offspring have purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple /lower/ round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
For each genotype listed, what allele combinations will occur in gametes? a. AABBCC b. AaBBc c. AaBBcc d. AaBbCc
Several alleles affect traits of roses, such as plant form and bud shape. Alleles of one gene govern whether a plant will be a climber (dominant) or shrubby (recessive). All F1 offspring from a cross between a true-breeding climber and a shrubby plant are climbers. If an F1 plant is crossed with a shrubby plant, about 50 percent of the offspring will be shrubby; 50 percent will be climbers. Using symbols A and a for the dominant and recessive alleles, make a Punnett- square diagram of the expected genotypes and phenotypes the cross between the F1 offspring and the shrubby plant.
In cladograms, sister groups are _______ . a. inbred b. the same age c. represented by nodes d. in the same family
The phenotype of individuals heterozygous for ________ alleles comprises both homozygous phenotypes. a. epistatic b. codominant c. pleiotropic d. hybrid
In cats, the genotype AA produces tabby fur color; Aa is also a tabby, and aa is black. Another gene at a different locus is epistatic to the gene for fur color. When present in its dominant W form (WW or Ww), this gene blocks the formation of fur color and all the offspring are white; ww individuals develop normal fur color. What fur colors, and in what proportions, would you expect from the cross AaWw Aa Ww?
Which of the following represents an example of qualitative phenotypic variation? a. the lengths of peoples toes b. the body sizes of pigeons c. human ABO blood types d. the birth weights of humans e. the number of leaves on oak trees
3. Choose ONE trait observed in class and explain why one form of the trait is more frequent than the other form of the trait (i.e. why the dominant form is more frequent than the recessive form or vis-à-vis).
