Atall pea plant (tt) is crossbred with a short pea plant (tt). the punnett square below shows the separated alleles for two pea plants. punnett square showing female parent across the top with a phenotype of tall and a genotype of tt and a male parent across the side with a phenotype of short and a genotype of tt. inside the top left box 1 is written, inside the top right box 2 is written, inside the bottom left box 3 is written, inside the bottom right box 4 is written. which of the following shows the correct match of the box numbers and the genotype of the offspring? 1 = tt; 2 = tt; 3 = tt; 4 = tt 1 = tt; 2 = tt; 3 = tt; 4 = tt 1 = tt; 2 = tt; 3 = tt; 4 = tt 1 = tt; 2 = tt; 3 = tt; 4 = tt

1. the passing of is the basis of heredity. 2. our encode the instructions that define our traits. 3. each of us has thousands of genes, which are made of and reside in our chromosomes. 4. in addition to our genes, the we live in also define our traits. 5. humans have two complete sets of chromosomes. 6. when parents conceive a child, each parent contributes set of chromosomes. 7. every child receives of its chromosomes from the mother and half from the father. 8. this transfer takes place at when the father’s sperm joins the mother’s egg. 9. while most cells in our bodies have two sets of chromosomes, or a total of egg and sperm each have chromosomes. 10. when egg and sperm unite they create a single cell called a 11. each parent contributes complete set of chromosomes to their child. 12. since the parents contribute the chromosomes to each new child, every child inherits a unique set of chromosomes. 13. as a result, every baby will have a combination of traits.
