Question 1
If a homozygous recessive pea plant (tt) is crossed with a heterozygous pea plant (Tt), what will be the genotypic and phenotypic ratios of the offspring?
💡 Hint: Create the Punnett square and fill it out to see the combinations.
Question 2
In a certain species of pea plants, yellow seeds (Y) are dominant over green seeds (y). If two heterozygous plants (Yy) are crossed, what are the expected ratios of offspring with yellow and green seeds?
💡 Hint: Use a Punnett square to derive the ratios from the alleles.
