Which of the following shows whorled phyllotaxy?
What does the filiform apparatus do at the entrance into the ovule?
Artificial insemination means:
Genes R and Y follow independent assortment. If RRYY produce round yellow seed and rryy produce wrinkled green seeds, what will be the phenotypic ratio of the F2 generation?
If two persons with 'AB' blood group marry and have the sufficiently large number of children, these children could be classified as 'A' blood group: 'AB' blood group: 'B' blood group in 1: 2: 1 ratio. The modern technique of protein electrophoresis reveals the presence of both 'A' and 'B' type proteins in 'AB' blood group individuals. This is an example of:
Change in the sequence of nucleotides in DNA is called:
Where is the respiratory electron transport system (ETS) located in plants?
In a plant, red fruit (R) is dominant over yellow fruit (r) and tallness (T) is dominant over shortness (t). If a plant with RRTt genotype is crossed with a plant that is rrtt, what percentage of the offspring will be tall with red fruit?
As per ABO blood grouping system, the blood group of father is B+, mother is A+ and child is O+. Their respective genotype can be
The allele for tallness is dominant over that of dwarfness. This is called:
The production of gametes by the parents, the formation of zygotes, the F1 and F2 plants can be understood using:
A tall true breeding garden pea plant is crossed with a dwarf true breeding garden pea plant. When the F1 plants were selfed, the resulting genotypes were in the ratio of:
"Saheli" is a(n)
The ovary is half inferior in:
Mental retardation in man occurs due to:
The fruit fly Drosophila melanogaster was found to be very suitable for experimental verification of the chromosomal theory of inheritance by Morgan and his colleagues because:
Match the terms in Column-I with their description in Column-II and choose the correct option. Column-I A. Dominance B. Codominance C. Pleiotropy D. Polygenic inheritance Column-II 1. Many genes govern a single character 2. In a heterozygous organism, only one allele expresses itself 3. In a heterozygous organism both alleles express themselves fully 4. A single gene influences many characters
