Question

genotype such as \pp\, didnt mean that its offspring had to inherit that same combination of alleles. now, he wanted to know if a plant with two traits (such as yellow seeds and a round seed - shape) could pass down one as opposed to both of their traits to their offspring. in other words, he wanted to know if the many different traits in a parent were tied together, forcing offspring to inherit a \package\ with all of that parents traits. cross two plants—each with two different purebred traits, to find out.
y = yellow pods

y = green pods

r = round seeds

r = wrinkled seeds

a purebred round - yellow - seeded pea plant will have a genotype of yyrr

what will be the genotype of the purebred wrinkled green - seeded pea plant?
dropdown with options: yyrr, yyrr, yyrr, ...

Explanation:

Step1: Recall purebred genotype rules

A purebred (homozygous) organism has two identical alleles for each trait. For pod color, green is represented by \( y \), so purebred green - podded plants have genotype \( yy \). For seed shape, wrinkled is represented by \( r \), so purebred wrinkled - seeded plants have genotype \( rr \).

Step2: Combine the genotypes for both traits

Since the plant is purebred for both green pods (trait 1) and wrinkled seeds (trait 2), we combine the two homozygous genotypes. The genotype for pod color is \( yy \) and for seed shape is \( rr \), so the overall genotype is \( yyrr \).

Answer:

\( yyrr \)
