2. In horses, black coat color is influenced by the dominant allele (B) and chestnut coat color is influenced by the recessive allele (b). Trotting gait is due to a dominant gene (T) and pacing gait to the recessive allele (t). If a homozygous black trotter is crossed to a chestnut pacer a. What is the appearance of the F1 and F2 generations? b. Which phenotype will be most common? Which genotype will be most common? c. Which of the potential offspring will be certain to breed true?

4. The ruffed chicken has an under-chin wattle. A smooth wattle (S) is dominant over a wrinkled wattle (s). A red wattle (HR) is incompletely dominant with a white wattle (HW) so that an individual with HRHW will have a pink wattle. A chicken with a wrinkled red wattle is mated to a homozygous chicken with a smooth white wattle. What is the genotype and phenotype of the chicks?
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.
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.)

6. Consider that people with blue eyes must have two alleles for blue eyes since blue eye color is a recessive trait. A blue-eyed person and a brown-eyed person have an offspring with blue eyes. The brown-eyed person must A. have two alleles for blue eyes. B. have two alleles for brown eyes. C. not have the dominant brown eye allele. D, have one allele for blue eyes and one allele for brown eyes.
2) In horses the color black is due to a dominant allele (B) and chestnut is due to the recessive allele (b). The trotting gait is due to a dominant allele (T) and the pacing gait to the recessive (t). a. What gametes would be produced by a homozygous black pacer? b. What gametes would be produced by a horse heterozygous for both traits?
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?
Imagine you are performing a cross involving seed color in garden pea plants. What Fi offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. 100 percent yellow-green seeds 100 percent yellow seeds 50 percent yellow, 50 percent green seeds 25 percent green, 75 percent yellow seeds
A true-breeding rabbit with agouti (mottled, grayish brown) fur crossed with a true-breeding rabbit with chinchilla (silver) fur produces all agouti offspring. A true-breeding chinchilla rabbit crossed with a true-breeding Himalayan rabbit (white fur with pigmented nose, ears, tail, and legs) produces all chinchilla offspring. A true-breeding Himalayan rabbit crossed with a true-breeding albino rabbit produces all Himalayan offspring. Explain the inheritance of the fur colors.
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 peas, the allele Le produces tall plants and the allele le produces dwarf plants. The Le allele is dominant to le. If a tall plant is crossed with a dwarf, the offspring are distributed about equally between tall and dwarf plants. What are the genotypes of the parents?

If your genotype is BB, what type of trait would you express as phenotype? a. dominant b. recessive c. both a and b d. neither a nor b 3. If a baby goat received a dominant gene for curly hair from one parent, and a recessive gene for straight hair from the other, which trait will the baby goat display? a. No hair b. Curly hair c.
