Question

genetic review
being tall (t) is dominant to short (t), the ability to eat dairy (d) is dominant to the non dairy eaters (d).
if 2 heterozygous parents have an offspring what would be the genotype for a heterozygous tall and a non dairy eating offspring
ttdd
ttdd
ttdd
ttdd

Explanation:

• For the height trait: Since being tall (T) is dominant to short (t), a heterozygous tall individual has the genotype Tt.
• For the dairy - eating trait: Since the ability to eat dairy (D) is dominant to non - dairy eaters (d), a non - dairy eating individual has the genotype dd.

Answer:

Ttdd (It seems there might be a typo in the options provided. If we assume the options are mis - labeled and we are looking for the combination of heterozygous tall (Tt) and non - dairy eating (dd), it should be Ttdd. Among the given options, if we consider a mis - labeling and assume the intended option is Ttdd which is closest to TtDd (if we assume a mis - print in the dairy part of the options), but strictly based on the description in the problem: heterozygous tall (Tt) and non - dairy (dd), the correct genotype is Ttdd. If we assume the options have a formatting error and the last option is supposed to be Ttdd (maybe written as TtDd by mistake), then the answer is the last option (assuming it was a mis - print). But if we go by the strict allele combination for heterozygous tall (Tt) and non - dairy (dd), it's Ttdd).
