| 8372193450 | cystic fibrosis | ________ ________________ (two words) is an inherited disorder that affects the lungs, digestive, and reproductive system and is inherited through a recessive allele. | 2 | |
| 8372193451 | dominant | A ________ allele is always expressed even if there is another allele present. | 3 | |
| 8372193452 | engineering | Genetic _________________ is the process by which scientists can add or remove genes from the genotype of an organism. | 4 | |
| 8372193453 | genotype | the genetic makeup of an individual for a particular characteristic, for example hair or eye colour. Dominant alleles are represented by capital letters. | 5 | |
| 8372193454 | heterozygous | individual who are __________________ have 2 different alleles for a characteristic. | 6 | |
| 8372193455 | homozygous | individual who are ________________ have two identical alleles for a characteristic. | 7 | |
| 8372193456 | meiosis | __________________is involved in making gametes for sexual reproduction. 4 daughter cells are produced. | 8 | |
| 8372193457 | phenotype | the physical appearance / biochemistry of an individual for a particular characteristic. is called the _________________________ | 9 | |
| 8372193458 | polydactyly | _________ is a dominant inherited disorder that results in babies born with extra fingers and/or toes. | 10 | |
| 8372193459 | Punnett | A _____________________ square diagram is a way of modelling a genetic cross and predicting the outcome using probability | 11 | |
| 8372193460 | recessive | a ________________ allele will only be expressed if an individual has 2 copies of it. | 12 | |
| 8372193461 | y | The x and __ chromosomes are called the sex chromosomes and carry the information that determines the sex of an individual. | 13 | |
