What is the expected phenotype of the offspring if the parents have the genotypes NN and nn?
All offspring will have normal wings
Which component of a genetic inheritance diagram is used to display the possible genotypes and phenotypes of the offspring?
The Punnett square
What is the purpose of a genetic inheritance diagram?
To illustrate the possible genotypes and phenotypes of the offspring
In a monohybrid cross, what are the possible genotypes of the F1 generation offspring when the parents have the genotypes Nn and Nn?
Nn, nn
What is the expected phenotypic ratio of the F2 generation offspring in a monohybrid cross when the F1 generation has the genotype Nn?
3:1 (normal:vestigial)
What is the genotype of the F1 generation offspring when the parents have the genotypes N,N and n,n in a monohybrid cross?
Nn
What is the expected phenotypic ratio of the F2 generation offspring in a monohybrid cross when the F1 generation has the genotype NN?
100% normal
What is the genotype of the F2 generation offspring in a monohybrid cross when the parents have the genotypes N,N and n,n?
NN, Nn, nn
What is the expected phenotypic ratio of the F2 generation offspring in a monohybrid cross when the F1 generation has the genotype nn?
100% vestigial
What is the expected phenotypic ratio for a monohybrid cross between a heterozygous parent (Bb) and a homozygous recessive parent (bb)?
1:1
If a cross between two heterozygous parents (Bb x Bb) produces an offspring with the recessive phenotype (bb), what is the genotypic ratio of the offspring?
1:2:1
If a plant with red flowers (RR) is crossed with a plant with white flowers (rr), what is the phenotypic ratio of the F1 generation?
All red
In a monohybrid cross, what is the probability of obtaining an offspring with the dominant phenotype if both parents are heterozygous?
1/2
If a plant with round seeds (RR) is crossed with a plant with wrinkled seeds (rr), what is the genotypic ratio of the F2 generation?
1:2:1
What is the test cross used for in monohybrid crosses?
To determine the genotype of an individual with a dominant phenotype
Test your knowledge on genetic diagrams, including codominance, monohybrid crosses, and Punnett squares. Explore how parent phenotypes/genotypes and gamete genotypes contribute to offspring genotypes and phenotypes.
