1. Albinism is autosomal recessive. If two carriers had 8 children, What are their genotypes and what would the genotypic and phenotypic ratios of their offspring be?
2. Looking at the rather large cow, what type of inheritance does she exhibit?
# 4 A. What type of inheritance is shown below? B. What are the genotypes of the Red, White and Pink? C. Cross 2 Pink flowers and records the offsprings’ genotypes and phenotypes
#5- A.The red blood cell in the picture is an example of what type of Inheritance? ______________ B.Cross a heterozygous type A with a heterozygous Type B and record offspring genotype and phenotypes
#6- Which of the bar graphs shown below BEST represents what the phenotypic frequencies might be for polygenic inheritance? A B C D
#7 A. What blood type is shown below? B. A. Dominant B. Recessive C. Codominant D. Incomplete Dominance
#8 - Alternate forms of the same gene are referred to as: A. telomeres B. centromeres C. sister chromatids D. Alleles
#9 - What phenotype is depicted in the figure below?
#10 - The combination of the alleles that are ALIKE are referred to as: A.Heterozygous B.Homozygous C.Endozygous D.Dominant
#11 - The combination of the alleles that are DIFFERENT are referred to as: A.Heterozygous B.Homozygous C.Endozygous D.Dominant
#12 This cow is the result of codominance. What is his phenotype and genotype of it’s parents?
#13 - A man heterozygous for blood type A marries a woman heterozygous for blood type B. What are the odds that their first child will have type O?
#14 - Eye color in humans is the result of : A.Codominance B.Incomplete Dominance C.Multiple Alleles D.Polygenic inheritance
# 15- White eyes in fruit flies are sex-linked recessive. If a female fruit fly heterozygous for red eyes crossed with a white-eyed male, what percent of their offspring would have A.white eyes? B.Red eyes?
# 16 - Both hemophilia and red-green color blindness are _____. A.Codominance B.Incomplete Dominance C.X-Linked D.Polygenic inheritance
X #17. What Mode of inheritance is below? A.Codominance B.Incomplete Dominance C.Multiple Alleles D.Polygenic inheritance Write the phenotypes of each smiley below the lines and the genotypes on, above, the lines for each on your answer sheet.
# 18- A female guinea pig homozygous dominant for black fur color is mated with a male homozygous recessive for white fur color. A.What are their genotypes? B.What are the genotypes and phenotypes of their offspring? X
#19 - In chickens, rose comb (R) is dominant to single comb (r). A.A homozygous rose-combed rooster is mated with a single-combed hen. What are the genotypes of this P generation? B.B. What are the genotypes of the F1 generation? C. All of the chicks in the F1 generation were kept together as a group for several years. They were allowed to mate only within their own group. What is the expected phenotypes of the F2 chicks?
#20 A.A colorblind man has children with a female carrier. Show cross in a punnett square. B.What proportion of females are colorblind? C. What proportion of males are colorblind?
# 21 What are the genotypic and phenotypic ratios of the offspring of a man with cystic fibrosis and female carrier?
#22 A pink carnation has one Red parent. Knowing this information you should know what type of inheritance this is! Use this information to: A. Cross two pink carnations. B. Write the genotypes with the corresponding phenotypes of each offspring!
# 23 A cross between a white rooster and a black hen results in checkered, Andalusian offspring (shown below). When an Andalusion rooster is crossed with a white hen, what percentage of offspring will be: a. White? b. Black? c. Andalusian?
#24 A heterozygous type B man and his type O wife have children. A. What are their Genotypes? B. What are the phenotypes of their offspring? Yes, this is a blood type question
# 25 A female carrier for hemophilia has children with a normal man. Draw the Punnett square. a.What proportion of ALL children will have hemophilia? b.How many females will have the disease? c.How many males? d.Why can males NOT be a carrier?
# 26 A person with an inherited disorder has a child with a person who does not have the disorder. Half of the children have the disorder, both males and females. The pattern of inheritance is ________. A. Autosomal DominantC. sex-linked B. Autosomal RecessiveD. Incomplete Dominant
