For how many years did Mendel conduct his experiments?

Answer 2

Seven years ( 1856 - 1863 )

Question 3

what is a true breeding line?

Answer 3

A plant having undergone self pollination, shows stable trait inheritance for several generations

Violet / white

Question 6

Question 9

Answer 9

Round / wrinkled

Question 10

what were the contrasting traits in :-

Seed colour

Answer 10

Yellow / Green

Question 11

What did Mendel observe in all F1 plants?

Answer 11

All F1 plants were tall, none were dwarf

Question 12

What happened when Mendel selfpollinated the tall F1 plants?

Answer 12

Some of the offsprings were seen dwarf

Question 13

Why were there no gametes in between height in the F2 generation?

Answer 13

Because the tall n dwarf type were similar to their parent type and didnt show any blending

Question 14

Alleles?

Answer 14

Genes which code for a contrasting pair of traits are called alleles

Question 15

What did Mendel earlier refer to genes as?

Answer 15

factors

Question 16

What is a homozygous condition?

Answer 16

When the allelic pair of genes are identical, it is a homozygous condiiton

Question 17

What is a heterozygous condition?

Answer 17

When the allelic pair of genes are not identical, it is a heterozygous condition.

Question 18

The production of gametes, and the formation of zygotes in the F1 and F2 generation can be understood by a ?

Answer 18

Punnett sqare

Question 19

Phenotypic ratio in a monohybrid cross?

Answer 19

3:1 ( tall:dwarf )

Question 20

Genotypic ratio

Answer 20

1:2:1

Question 21

What is a back cross?`

Answer 21

unknown plant crossed with its parent is called back cross

Question 22

What is a test cross?

Answer 22

unknown plant x recessive parent is called test cross
