Which of the following characters were analysed by Gregori Mendel in his studies?
seed colour
seed shape
flower colour
stem length
If we cross two heterozygous plants (RrAa) for two characters (R red flower, r blue flower, A long stem, a short stem) What will be the proportion of phenotypes in the offspring?
9:3:3:1
There will be only one phenotype. 100%
3:1
1:2:1
Mendel crossed purebred yellow seeds with purebred greenseeds. Then he self ferilised the F1 progeny to obtain the F2. The statistic analysis of the F2 showed that... (more than one answer might be right)
100% of the F1 and 75% of the F2 were yellow.
All seed were yellow.
50% of F1 and 75% of F2 were yellow.
Green colour disappeared in the F1 but reappeared in F2
What does first Mendel's laws state?
When crossing two purebred individuals the phenotype of the offspring is homogeneus and corresponds to the dominant trait.
When crossing two purebred individuals the phenotype of the offspring is homogeneus and corresponds to the recessive trait.
When crossing two hybrids showing the dominant phenotype, the recessive trait reappears in the offspring.
The offspring will look like parentals.
Which is the expected phenotype if we cross two purebred plants with yellow and green seeds?
100% green seeds
100% yellow seeds
75% yellow seeds 25% green seeds
75% green seeds 25% yellow seeds
Second Mendel's law states that...
The offspring from two hybrids with the same phenotype, includes individuals with a different phenotype from the parentals.
There is a uniform inheritance of characters. The progeny is identical to the parentals.
The offspring from two purebred individuals is homogeneus and shows the same phenotype as one parental only.
Phenotype and genotype are the same.
Which of the following patterns of inheritance is characterized by the presence of two dominant alleles that are both fully expressed in the phenotype?
Incomplete dominance
Codominance
Complete dominance
Recessive inheritance
In a dihybrid cross between two heterozygous individuals (AaBb x AaBb), what is the expected phenotypic ratio of the offspring?
9:3:3:1
3:1
1:2:1
1:1
A woman with blood type A (genotype AO) and a man with blood type B (genotype BO) have a child. What are the possible blood types of their child?
A, B, AB, O
A, B
AB only
O only
