If the pedigree is studying an autosomal recessive condition for which the alleles are A and a, what was the probability that a child produced by parents A and B would be heterozygous?

Correct Answer: 0.5000
D-The mother (person B) must be heterozygous Aa because she and her husband (aa) have produced children that have the double recessive condition. This means that person B (the mother) must have contributed an a and that the cross is Aa ×aa-and the probability is 1/2.

If you cross homozygous recessive short plant with heterozygous purple flower to heterozygous tall plant with heterozygous purple flower, what will be the expected phenotypic ratio?

Consider the following statements
In pedigree method of breeding
1. plant selection is continued till the progenies become homozygous.
2. plants are selected from F2 on words and their progenies are tested.
3. it may be possible to study precise nature of inheritance of different characters by studying the pedigree records.
Which of the statements given above are correct?

You know that H is dominant for height locus and H is recessive. Is the F2 progeny are a mixture of 3:1 dominant: recessive and you pick a dominant plant at random what will be the probability that the F3 will have a mixture of dominant and recessive traits as well?

Which of the following are salient features of Parent Education?
1. Non-involvement of parents leads to better grades in children.
2. Involvement of parents leads to better grades of children.
3. Education of children and parents is interdependent.
4. Parents do not care for their child's cognitive development.
5. The Adult Education and Family Literacy Act reflects dual goal.

If the dominant alleles of the two or more pairs of linked genes are present on one chromosome and their recessive alleles of all of them on the other homologue, this arrangement is known as

In a cross between wild type pure breeding recessive and heterozygous dominant trait, if 4 progeny are found to be expressing the dominant phenotype, what will be the expected number of recessive?

In mouse agouti locus is hypostatic to pigment development locus. If C is for pigment development, and A is for agouti, and recessive alleles in agouti locus gives black colour and recessive in pigment locus gives white colour, what will be the phenotype of A/- c/c and a/a c/c.

Which of the following statement(s) is/are true?
1. Thumb sucking makes child feel secure.
2. Thumb sucking relieves the child's stress.
3. Child abuse is necessary to discipline the child.
4. Parents can abuse the child any time.

A, is in a house which is on fire, with Z, a child. People below hold out a blanket. A drops the child from the house-top, knowing it to be likely that the fall may kill the child but not intending to kill the child, and intending, in good faith, the child's benefit, and the child dies:
Which of the following offence has been committed by A?
