A heterozygous plant is crossed with a short plant. What are the genotypes of the offpsring and how often do they occur
I know the genotypes are Tt and tt but I don't understand what they mean by how often do they occur
The question is asking about the chances of offspring produce which is two of Tt and two of tt so the chance is 50:50 that is 1:1
Heterozygous = 2 different alleles Homozygous = 2 of the same alleles. The short plant is usually heterozygous for the recessive trait (short), which is indicated with a lowercase letter (t) So the genotype of the short plant is tt Heterozygous for 1 trait means 2 different alleles, 1 dominant (uppercase letter) and 1 recessive allele (Tt). To find out what the offspring is, you draw a punnett square. I'll draw one for example:|dw:1406070011054:dw| So the 2 different genotypes of the offspring are Tt and tt, which occur equally. So a 1:1 ratio.
