1.
There is a gene for height in a species of pea plant that we will
call "T gene". We would denote the dominant allele for this gene as
_____ and the recessive allele as _____. A homozygous dominant
individual's genotype would be _____, a homozygous recessive
individual's genotype would be _____, and a heterozygous
individual's genotype would be _____.
2. If this gene for height in pea plants shows complete

In pea plants, height is controlled by a single gene and the tall allele (T) is dominant to the short allele (t). You find a tall pea plant in your yard and cross it with a short pea plant. It gives rise to 43 tall offspring and 35 short offspring. What is the genotype of the tall parent plant? Answers: Tt tt TT

8. Let's say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes long whiskers & the recessive allele (w) codes for short whiskers. What percentage of offspring would be expected to have short whiskers from the cross of two long-whiskered seals, one parent is homozygous dominant and the other one is heterozygous? If one parent seal is pure long-whiskered and the other is short-whiskered, what percent of offspring would have...

2) In wild yarrow, short plants are genetically recessive; tall plants are dominant a) A short plant is pollinated by a heterozygous tall plant. What genotypic and phenotypic outcomes would you expect for their offspring? b) A homozygous tall plant is pollinated by a heterozygous tall plant. What genotypic and phenotypic outcomes would you expect for their offspring?
