Inheritance
Identifying various forms of inheritance
| Question | Answer |
|---|---|
| A plant species has two alleles for flower color: Red (R) and White (r). The Red (R) allele exhibits complete dominance. A (RR) male is crossed with a recessive female. Identify the probability that an offspring will be homozygous dominant? | 0% |
| Scientists call an organism that has two different alleles for a trait | Heterozygous |
| DNA sequences that control traits are called | Genes |
| If alleles are written TT, it means the organism would be | Homozygous Dominant |
| If alleles are written tt, it means the organism would be | Homozygous Recessive |
| Long radishes crossed with round radishes result in all oval radishes. This type of inheritance is: | Incomplete Dominance |
| A cross of a white chick (WW) with a black chick (BB) produces all speckled offspring (WB) This type of inhetitance is known as: | Codominance |
| If a homozygous white guinea pig (bb) is crossed with a homozygous white guinea pig (bb), what is the probability that the offspring will have black hair? | 100% |
| An organisms physical appearance is its | Pheonotype |
| An organisms actual genes is its | Genotype |
| What does a Punnett Square show? | A model of the possible outcomes of a genetic cross. |
| Which combination will result in an offspring being female? | XX |
| If two white sheep produce a black offspring, the parent’s genotypes for color must be: | Heterozygous |
