Mendel used the garden pea plant for his hybridization experiment because:
- It is easy to grow
- It has easily distinguishable and inheritable characters
- It has a very long life span
- It is easily self pollinated
In a breeding experiment, a pea plant producing yellow seeds is crossed with a green-seeded pea plant. All the F1 plants are yellow-seeded. If these F1 plants are crossed with the green-seeded parent plant, the progeny consists of
All yellow seeded plants
Yellow seeded and green seeded plants in 3:1 ratio
All green seeded plants
Yellow seeded and green seeded plants in 1:1 ratio
- mRNA
- rRNA
- DNA
- phosphate molecule
In pea plants, round seed is dominant over wrinkled seed. A plant with different alleles for round seeds was crossed with a plant with same alleles of wrinkled seeds. Which of the following can be the expected result?
301 round and 100 wrinkled
305 round and 301 wrinkled
200 round and 100 wrinkled
99 round and 300 wrinkled
How many types of gametes are produced by the parents of Mendel’s monohybrid F2 progeny?

Three
Two
Four
In a plant, the red colour of the flower is dominant over white. A cross was made between a plant containing red flower and other with white flower. The cross yielded 50% white-flowered plant and 50% red flowered plant. The trait of the parent with the red flower has:
Homozygous
Heterozygous
Cannot be determined
Can be homozygous or heterozygous
