Part A - Deducing phenotypes and genotypes of selfed parents
Mendel studied pea plants dihybrid for seed shape (round versus
wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele
(r) and
the yellow allele (Y) is dominant to the green allele
(y).
The table below shows the F1 progeny that result from
selfing four different parent pea plants.
Use the phenotypes of the F1 progeny to deduce the
genotype and...
In this tutorial you will examine dihybrid crosses: crosses
where alleles at separate loci assort independently into gametes at
meiosis. You will also use logic to determine unknown genotypes,
phenotypes, and genetic ratios from given data.
Part A - Deducing phenotypes and genotypes of selfed parents
Mendel studied pea plants dihybrid for seed shape (round versus
wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele
(r) and
the yellow allele...
Mendel found that round (R) seed is dominant over wrinkled (r) seed, and yellow (G) seed is dominant over green (g) seed. The following crosses were made between plants of known phenotypes but unknown genotypes: a) Using the same symbols as defined above, list the genotypes of the parent plants in each cross. 1 round, yellow X round, yellow 2 round, yellow X round, yellow 3 round, yellow X wrinkled, green b) Which of the above crosses is a...
Part B - Deducing genotypes of crossed parents A plant grown from a [round, yellow] seed is crossed with a plant grown from a [wrinkled, yellow] seed. This cross produces four progeny types in the F [round, yellow], [wrinkled, yellow], [round, green], and [wrinkled, green]. Use this information to deduce the genotypes of the parent plants. Indicate the genotypes by dragging the correct label to the appropriate location.
A plant grown from a [round, yellow] seed is crossed with a plant
grown from a [wrinkled, yellow] seed. This cross produces four
progeny types in the F1:
[round, yellow], [wrinkled, yellow], [round, green], and [wrinkled,
green].
Use this information to deduce the genotypes of the parent
plants.
Here is what the question looks like if that helps: All it is
asking for is the 2 parent genotypes but I'm not sure of the
answer... if someone can explain and...
Hope someone can help me with this. Thanks!

Question 1. Consider 3 gene loci in the pea plant. Locus 1 affects seed color; allele G for green, g for yellow. Locus 2 affects seed shape; allele R for round, r for wrinkled. Locus 3 affects flower color; allele B for red, b for white. Each uppercase allele is completely dominant to their corresponding lowercase, recessive allele. Each locus is on a different non-homologous chromosome; so, the loci segregate or sort independently from each other during meiosis. Two parent...
In one of Mendel's experiments he crossed two rule breeding pea plants. One produces yellow and round seeds and the other produces green and wrinkled seeds. Yellow and round are dominant traits whereas green and wrinkled are recessive. We will classify yellow as ''Y'' green as ''y'' round as ''R'' and wrinkled as "r" In part A show F1 generation using punnet square. In part B show a punnet square for F2 generation from dihybrid cross. In part C by...
Question 31 (1 point) In pea plants, round (R) seeds are dominant to wrinkled (r) seeds. In a genetic cross of two pea plants where one plant is heterozygous for the seed shape trait and the other is homozygous for the recessive (r) trait, what percentage of the offspring would have the wrinkled seed shape? O a) 25% Ob) 100% O c) 50% O d) 75% Question 32 (1 point) In pea plants, green (G) seeds are dominant to yellow...
