One parent is Tt and the other is tt. In the square, a T sperm meets a t egg. What genotype belongs in that box?
In a Bb × Bb cross, the lower-right box combines a b sperm and a b egg. What offspring genotype should fill that box?
A Rr parent and an RR parent are crossed. In one box, an R sperm meets an R egg. What genotype goes there?
For a Gg × gg cross, the left top box combines G from one parent with g from the other. What genotype should be written?
In an Aa × aa Punnett square, a box combines a and a. What offspring genotype is formed?
Two Hh plants are crossed. In a box where H from one gamete meets h from the other, what genotype is entered?
In a Pp × pp cross, the right bottom box receives p from both parents. What genotype belongs in that box?
In pea plants, T is tall and t is short. Use the Tt × Tt Punnett square. What chance of tall offspring is predicted?
Black fur B is dominant over white fur b in mice. Use the Bb × bb Punnett square. What chance of black fur is predicted?
In peas, R is round and r is wrinkled. Use the RR × rr Punnett square. What chance of wrinkled offspring is predicted?
Purple flower P is dominant over white p. Use the Pp × Pp Punnett square. What chance of white flowers is predicted?
Green pod G is dominant over yellow pod g. Use the GG × gg Punnett square. What chance of green pods is predicted?
Solid coat S is dominant over spotted coat s. Use the Ss × ss Punnett square. What chance of spotted offspring is predicted?
Smooth seed F is dominant over wrinkled f. Use the Ff × Ff Punnett square. What chance of smooth seeds is predicted?
In a plant trait, M is long leaves and m is short leaves. Use the mm × mm Punnett square. What chance of short leaves is predicted?
Two purple-flowered pea plants have some white-flowered offspring. Purple P is dominant and white p is recessive. What must each parent genotype be?
A hamster cross gives about half curly-haired and half straight-haired offspring. Curly H is dominant, and straight h is recessive. What parent genotypes fit this pattern?
A Punnett square has four Aa boxes; every offspring gets A from one parent and a from the other. What parent genotypes made that square?
A rabbit litter from a one-gene trait shows only white fur, the recessive b phenotype. What parent genotypes would make every offspring bb?
For a seed trait, one parent makes only B gametes and the other makes B and b gametes. The square has BB and Bb boxes. What are the parent genotypes?
