Monohybrid Crosses Other Crosses I Other Crosses II Random

Row 1, Col 1 Define phenotype. Physical Appearance of an individual

1,2 How many traits does a dihybrid cross look at? Two

1,3 Where are sex linked genes located? On the sex chromosome or X chromosome

1,4 An individual possess two identical alleles for a trait. This person is said to be __________ for the trait. Homozygous

2,1 Brown eyes is dominant to blue eyes. A woman with brown eyes who is homozygous, marries a man with blue eyes. Write out the genotypic ratio. 4/4 will be Bb or heterozygous

2,2 Smooth is dominant over wrinkled Green is dominant over yellow What are genotypes of the parents If a heterozygous smooth Heterozygous green is crossed with A wrinkled yellow? Ss Gg X ss yy

2,3 Mary has wavy hair but her Father has straight and mother Has curly. What type of Inheritance is this? Incomplete Dominance

2,4 Which of Mendel’s laws focuses on the idea that traits are Inherited separately. Principle of Independent Assortment

3,1 In dogs, long hair is dominant To short hair. Please give the Genotypic and phenotypic ratios Of a short hair dog crossed with A heterozygous long hair dog 2/4 Ll; 2/4 ll  2/4 long and 2/4 short

3,2 When a brown cow is mated with A white cow, a roan (spotted) cow Is produced. What kind of inheritance Is this? codominance

3,3 A woman with blood type O marries a man with blood type B. What are the possible blood types of their offspring? O or B

3,4 Define a test cross. Used to determine if dominant individual is homozygous or heterozygous  mate with a homozygous recessive

4,1 Why do we use a punnett square? Determine the probable outcome of a cross

4,2 Name two diseases or conditions that are sex linked Answers will vary

4,3 A woman does not have hemophilia in her family but she marries a man who has hemophilia. What is the chance that their son will be normal? 100%

4,4 Define the principle of dominance. One trait is dominant over the other and covers that trait

5,1 How does incomplete Dominance differ from a “normal” Punnett square? Blending of trait in heterozygous form

5,2 In a dihybrid cross, if the first Parent is heterozygous and the Second is recessive for both traits, How many different genotypes are Possible in the offspring? four

5,3 A woman with blood type A Marries a man with blood type B. Their son has O blood. Is this Possible? Explain Yes because the parents can be heterozygous and both Pass on O allele

5,4 A man has AB blood and a woman Has B Blood. What are the Possible blood types their Children could have? A, B, AB
