Genetics & Heredity
Unit 5: Genetics & Heredity
| Question | Answer |
|---|---|
| What is true about two parents who show a recessive trait? | all of their offspring will show a recessive trait |
| What is the process that is commonly used to assure desirable characteristics, or traits, in the offspring of animals? | selective breeding |
| Within a species, a number of characteristics remain the same from one generation to the next. What would explain this? | Characteristics are genetic |
| Two blue flowers were crossed, and the resulting offspring were 75 % blue and 25% green. Which term describes the green flower color? | recessive |
| When Gregor Mendel crossed pea plants that produced yellow seeds with pea plants that produced green seeds, he observed plants that produced only yellow seeds among the offspring . Which term describes the trait for producing yellow seeds? | completely dominant |
| A woman with brown hair and a man with brown hair have a baby with blonde hair. The allele for having blond hair must be.... | recessive |
| When alleles are the same, the are ______________. | homozygous |
| When alleles are different, the are _______________. | heterozygous |
| The passing of traits from parent to offspring is called ____________. | heredity |
| Characteristics such as eye color, that are passed from one generation to the next, are known as ______. | traits |
| This kind of allele is always represented by a capital letter. | Dominant |
| This situation is when one trait is not completely dominant over the other. It is a blending of the traits. | Incomplete Dominance |
| When a bacterial cell splits to form tow new bacterial cells, is this sexual or asexual reproduction? | asexual |
| How many parent cells are involved when an organism reproduces asexually? | 1 |
| How many parent cells are involved when an organism reproduces sexually? | 2 |
| The purpose of meiosis is to make these. | Sex Cells, Gametes, Reproductive Cells, Haploid Cells |
| The purpose of Mitosis is to produce these. | Body Cells, Somatic Cells, Diploid Cells |
| Which type of reproduction involves 2 parents and the offspring are not genetically identical? | Sexual Reproduction or Fertilization |
| List some examples of asexual reproduction. | regeneration, binary fission, budding |
| How many new cells form from mitosis? | 2 |
| How many new cells are formed from meiosis? | 4 |
| Individuals in a population that have traits or abilities that give them a competitive advantage over other population members are more likely to survive and reproduce. What principle is this? | Natural Selection |
| What process creates cells with half of the DNA? | Meiosis |
| What process makes new identical cells? | Mitosis |
| What process is used to assure desirable traits in offspring? | Selective Breeding |
| If a sexually reproducing organism has 14 chromosomes in its DNA, how many did it get from each parent? | 7 |
| Genetic mutations can be..... | harmful, beneficial, or neither (neutral) |
