Question

which represents the cross between parent plants if one is heterozygous and has yellow - colored pods is homozygous and has green - colored pods?
○ yy`yy
○ yy`yy
○ yy`yy
○ yy`yy

Explanation:

Step1: Recall the definition of heterozygous and homozygous

Heterozygous means having two different alleles (e.g., \(Yy\)), and homozygous means having two identical alleles (e.g., \(yy\) or \(YY\)).

Step2: Analyze each option

• For \(Yy\times yy\): One parent is heterozygous (\(Yy\)) and the other is homozygous (\(yy\)).
• For \(YY\times yy\): One parent is homozygous (\(YY\)) and the other is homozygous (\(yy\)).
• For \(Yy\times Yy\): Both parents are heterozygous (\(Yy\)).
• For \(yy\times yy\): Both parents are homozygous (\(yy\)).

Answer:

\(Yy\times yy\) (the first option)
