In true breeding, the allelic pair of genes are:
1. | Homologous | 2. | Linked |
3. | Stable | 4. | Homozygous |
What could be the genotype of a garden pea plant that expresses the tall trait of height?
1. | TD | 2. | Tt |
3. | Td | 4. | tt |
In a dissimilar situation, the unit factor that expresses itself is called as:
1. | Dominant | 2. | Recessive |
3. | Epistatic | 4. | Hypostatic |
A plant with the genotype Tt should be called:
1. | Heterologous | 2. | Hemizygous |
3. | Heterozygous | 4. | Dihybrid |
A genetic cross between homozygous individuals but with different alleles for a single gene of interest is called as:
1. | A reciprocal cross | 2. | Monohybrid cross |
3. | Dihybrid cross | 4. | Test cross |
Identify the incorrect statement:
1. | Tall plant produces gametes by meiosis and the dwarf plant by mitosis. |
2. | Only one allele is transmitted to a gamete. |
3. | This segregation of alleles is a random process. |
4. | Gametes will always be pure for the trait. |
A heterozygous plant produces:
1. | Only one kind of gamete |
2. | Two kinds of gametes, each having one allele with equal proportion. |
3. | Two kinds of gametes, each having two alleles with equal proportions. |
4. | Two kinds of gametes, each having one allele, with one allele occurring in more gametes than the other. |
A graphical representation to calculate the probability of all possible genotypes of offspring in a genetic cross is called as:
1. | Forked line diagram | 2. | Punnett square |
3. | Pedigree chart | 4. | Idiogram |
What proportion of progeny in F2 generation in a Mendel monohybrid cross resembled the parent [of P generation] that expressed the recessive trait?
1. | ¼ | 2. | ½ |
3. | ¾ | 4. | 2/3 |
The F2 genotypic ratio of a monohybrid cross is:
1. | 1 : 1 | 2. | 3 : 1 |
3. | 1 : 2 : 1 | 4. | 9 : 7 |
