If an organism with the genotype Ww is crossed with a Ww organism, what would be the proportion of offspring that would be heterozygous?
Correct answer: B. 2/4
- A. 1/4
- B. 2/4
- C. 3/4
- D. All would be heterozygous
Explanation
When they are crossed one will be homozygous dominant 2 are heterozygous and one is homozygous recessive so the proportion of heterozygous will be 2/4.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
