Chapter 10, Problem 4GP

Two lizards have green skin and large dewlaps (genotype Gg Dd). (a) If 32 offspring are born, how many of the offspring are expected to be homozygous recessive for both genes? (b) What proportion of the offspring will have the dominant phenotype for both traits? (Assume that the traits assort independently.)

Peas heterozygous for three independently assorting genes were intercrossed. (a) What proportion of the offspring will be homozygous for all three recessive alleles? (b) What proportion of the offspring will be homozygous for all three genes? (c) What proportion of the offspring will be homozygous for one gene and heterozygous for the other two? (d) What proportion of the offspring will be homozygous for the recessive allele of at least one gene?
The achoo syndrome (sneezing in response to bright light) and trembling chin (triggered by anxiety) are both dominant traits in humans.a. What is the probability that the first child of parents who are heterozygous for both the achoo gene and trembling chin will have achoo syndrome but lack the trembling chin?b. What is the probability that the first child will have neither achoo syndrome nor trembling chin?
Black eye (B) is dominant over brown eye (b). A man that is a homozygous dominant black-eyed marries a woman that is a heterozygous black-eyed. The offspring resulted to 50% homozygous black and 50% heterozygous black. If one of their heterozygous children marries another heterozygous partner. Regardless of its gender, what are the genotypes of their children?     a. 25% BB, 50% Bb, 25% bb b. 50% BB, 25% Bb, 25% bb c. 25% BB, 25% Bb, 50% bb d. 0% BB, 75% Bb, 25% bb         In Law of Codominance, a pure line dominant trait crossed with a recessive trait will result to the appearance of both dominant and recessive trait in the offspring. What is the percentage of having a red-haired offspring if the parental genotype is both a heterozygous roan haired? Red hair is a dominant trait and white hair is a recessive trait.     a. 100% b. 75% c. 50% d. 25% e. 0%
