Q5. When Mendel crossed a large number of tall pea plants with short pea plants, all F1 plants
were tall. The F2 generation was created by self-pollinating the F1 plants.
(a) Complete a genetic cross of F1 to show the genotypes and phenotypes of the parents and
offspring.
(b) Complete a genetic cross of F2 to show the genotypes and phenotypes of the offspring.
(c) State the ratio of phenotypes expected in the F2 offspring.
(d) Mendel's First Law of inheritance states that, “...the alleles of a given locus segregate into
separate gametes." Explain how the genetic diagram above proves this law. (AC 2.1)
Part 1: Make a three part process drawing (like a cartoon strip) to demonstrate Mendel’s Principle of Segregation. Use two parents with homologous chromosomes marked with alleles “A” and “a”.
Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes (indicate when this happens), and c) gametes from each parent combine at random to form diploid offspring
Part 2: Use the cross Aa x Aa and a Punnett square to demonstrate Mendel’s Principle of Segregation. Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes and c) gametes from each parent combine at random to form diploid offspring. Write the expected genotypic and phenotypic ratios.

One homozygous strain, Il ww hh, has leaves that are 100 mm in length, and the other strain, LL WW HH, has 220 mm leaves. The two homozygous strains are crossed, and the resulting F₁ are selfed to produce F₂ progeny.
