Question
trait such as \tt\ is said to be heterozygous
rr
yy
rr
yy
homozygous
rr
pp
pp
rr
tt
heterozygous
tt
tt
To solve this problem, we need to classify the given genotypes as homozygous or heterozygous. A homozygous genotype has two identical alleles (e.g., \(RR\), \(pp\), \(YY\), \(TT\)), while a heterozygous genotype has two different alleles (e.g., \(Tt\), \(Yy\), \(Rr\), \(rR\)).
Step 1: Identify Homozygous Genotypes
- \(RR\): Both alleles are \(R\) (identical) → Homozygous.
- \(PP\): Both alleles are \(P\) (identical) → Homozygous.
- \(pp\): Both alleles are \(p\) (identical) → Homozygous.
- \(rr\): Both alleles are \(r\) (identical) → Homozygous.
- \(TT\): Both alleles are \(T\) (identical) → Homozygous.
- \(YY\): Both alleles are \(Y\) (identical) → Homozygous.
Step 2: Identify Heterozygous Genotypes
- \(Tt\): Alleles \(T\) and \(t\) (different) → Heterozygous.
- \(Yy\): Alleles \(Y\) and \(y\) (different) → Heterozygous.
- \(Rr\): Alleles \(R\) and \(r\) (different) → Heterozygous.
- \(rR\): Alleles \(r\) and \(R\) (different) → Heterozygous.
Final Classification:
- Homozygous: \(RR\), \(PP\), \(pp\), \(rr\), \(TT\), \(YY\)
- Heterozygous: \(Tt\), \(Yy\), \(Rr\), \(rR\)
If the task was to sort the left - hand list (\(rR\), \(Yy\), \(Rr\), \(YY\)):
- \(rR\): Heterozygous (different alleles \(r\) and \(R\))
- \(Yy\): Heterozygous (different alleles \(Y\) and \(y\))
- \(Rr\): Heterozygous (different alleles \(R\) and \(r\))
- \(YY\): Homozygous (same allele \(Y\))
If we assume the task is to place the left - hand genotypes into the correct boxes:
- Homozygous Box: \(YY\)
- Heterozygous Box: \(rR\), \(Yy\), \(Rr\)
