| Question | Answer |
|---|---|
| In humans the trait of having freckles (F) is dominant to not having freckles (f). Which genotype and phenotype are correctly paired? | Ff—freckles |
| The allele for tasting PTC (T) is dominant to the allele for nontasting PTC (t). Which of these sets of parents can produce offspring who cannot taste PTC? | a heterozygous male who can taste PTC and a heterozygous female who can taste PTC |
| What results in the separation of chromosomes randomly and independently during the production of sperm and egg cells (meiosis)? | independent assortment |
| The allele for attached earlobes (e) is recessive to the allele for unattached earlobes (E). A woman with the genotype (Ee) and a man with the genotype (ee) have a child. What is the probability that the child is heterozygous for this trait? | 50% |
| During prophase I, sections of homologous chromosomes switch places. What is this process called? | crossing over |
| Sex cells are produced during | meiosis |
| A sperm cell of a fruit fly has 4 chromosomes. How many chromosomes are in the cells of a fruit fly’s leg? | 8 |
| How many chromosomes are in a normal human skin cell? | 46 |
| Which of these represents the number of chromosomes in cells before and after the process of meiosis? | 2n -> n |
| One parent is homozygous dominant for brown hair (BB). The other parent is heterozygous for brown hair (Bb). What is the probability that the offspring will have brown hair? | 100% |
| In guinea pigs, the allele for black fur (B) is dominant. A homozygous guinea pig (BB) is crossed with a heterozygous guinea pig (Bb). What are the phenotypes of the parents? | Both parents have black fur. |
| Which processes of cell division creates genetic diversity? | meiosis |
| What process produces male and female reproductive cells in plants? | meiosis |
| WHAT IS TRAIT? | A VARIATION OF A PATICULAR CHARACTER |
| PARTICULATE HYPOTHESIS SAY THAT : | PARENTS PASS ON TO THEIR OFFSPRING SEPARATE AND DISTINCT FACTORS(GENES) THAT ARE RESPONSIBLE FOR INHERITED TRAITS |
| BIOLOGISTS PROPOSED THE BLENDING HYPOTHESIS WHICH SAY : | OFFSPRING WOULD BE A BLEND OF PARENTS TRAITS |
| BOTH BLENDING AND PARTICULATE HYPOTHESIS TRY TO EXPLAIN THE INHERITANCE OF TRAITS | TRUE |
| PARTICULATE HYPOTHESIS STATES THAT PARENTS PASS ON DISTINCT FACTORS THAT RETAIN THEIR IDENTITIES IN OFFSPRING | TRUTH |
| BLENDING HYPOTHESIS STATES THAT | PARENTS' HEREDITARY MATERIAL BLENDS IN THE OFFSPRING |
| WHAT IS CALL WHEN THE SPERM FROM ONE INDIVIDUAL FERTILIZE THE EGGS OF ANOTHER INDIVIDUAL? | CROSS FERTILIZATION |
| WHAT IS CALL Fusion of male and female sex cells (gametes) produced by the same individual ? | SELF FERTILIZATION |
| WHAT IS THE NAME FOR OFFSPRING OF 2 DIFFERENT TRUE BREEDING VARIETIES LIKE - PARENTAL PLANTS = P GENERATION - HYBRID OFFSPRING = F1 GENERATION ? | HYBRIDS |
| WHAT IS A NAME FOR PARING IN WHICH THE PARENT PLANT DIFFER IN ONLY ONE TRAIT? | MONOHYBRID CROSS |
| ALLELES ARE | ALTERNATIVE FORMS OF GENES |
| HOMOZYGOUS ARE : | THE 2 ALLELES FOR A GENE ARE THE SAME DD OR dd |
