Predicting the possible genotypes of offspring✓Bonne réponse
Recording the genotypes of offspring that have been born
Measuring how tall the offspring will grow
Counting how many chromosomes a body cell contains
Explication
The diagram starts from the alleles the parents can pass on and sets out every combination their gametes could produce, before any offspring exist. A record of offspring already born is data gathered afterwards, so it reports what happened rather than what the cross makes possible.
