In the offspring of the two sunflowers above, determine the likely ratio of homozygous tall to heterozygous genotypes. 1:11:2:11:33:1I'm not sure

1. Break Down the Problem

To determine the genotype ratio of the offspring from two sunflowers, we need to start by identifying the genotypes of the parents and then apply the principles of Mendelian genetics. The typical scenario includes identifying the tall (T) and short (t) traits.

2. Relevant Concepts

• Homozygous (TT or tt): When both alleles are the same.
• Heterozygous (Tt): When the two alleles are different.
• Punnett Square: A diagram that is used to predict the genotype of an offspring from two parents.

3. Analysis and Detail

Assuming the two parent sunflowers are heterozygous tall (Tt x Tt):

• Possible gametes from both parents: T and t
• Constructing a Punnett Square for Tt x Tt:

From the Punnett Square:

• TT (homozygous tall): 1
• Tt (heterozygous tall): 2
• tt (homozygous short): 1

Total Ratio:

• Homozygous tall (TT): 1
• Heterozygous tall (Tt): 2
• Homozygous short (tt): 1

Thus the ratio of homozygous tall to heterozygous tall is:

• Homozygous Tall (TT): 1
• Heterozygous Tall (Tt): 2

4. Verify and Summarize

To verify, we see that when two heterozygous parents are crossed, we obtain the aforementioned ratios. The ratio for homozygous tall to heterozygous genotypes is 1:2.

Final Answer

The likely ratio of homozygous tall to heterozygous genotypes is 1:2.
