Equal genetic contribution of male and female parents in the progeny is ensured by the equal inheritance of chromosome from each parent. Human possesses 23 pairs of chromosomes, of which 22 pairs are autosomes and 1 pair is the sex chromosomes. The two sex chromosomes in human are X and Y. Females have 2 X chromosomes and males have a X and Y ...

A Mendelian experiment consisted of breeding tall pea plants bearing violet flowers with short pea plants bearing white flowers. The progeny all bore violet flowers, but almost half of them were short. This suggests that the genetic make-up of the tall parent can be depicted as (a) TTWW (b) TTww (c) TtWW (d) TtWw
The sex linked recessive disease shows its transmission from unaffected carrier female to some of the male progeny e.g., haemophilia. The heterozyous female (carrier) of haemophilia may transmit the disease to sons.
The progeny is self-pollinated. The ratio of true breeding tall Pea plants to true breeding dwarf Pea ...
A pure homozygous line, obtained by continuous self-pollination is called a. View Solution. Q 4. Question 2. Two pink coloured flowers on crossing resulted in 1 red, 2 pink and 1 white flower progeny. The nature of the cross will be. (a) double fertilisation. (b) self pollination. (c) cross fertilisation.
Assertion :Test cross is the cross between the F 1 progeny and either of the parent types. Reason: Back cross is the cross between F 1 progeny and the double recessive genotype. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
64. Solution. Verified by Toppr. When a cross is made between AABBCC and aabbcc, an F1 progeny with AaBbCc is formed. When it is subjected to self fertilization, 8 types of gametes are formed. They are ABC, ABc, AbC, Abc, aBC, aBc, abC, abc.
Pure line is a self-pollinated progeny of single homozygous plant. These plants are homozygous due to some genotype. To obtain a pure line, a pure line selection is carried out. In this, large numbers of plants are selected from self-pollinated plants and harvested individually. The pure line progeny obtained from all these plants are evaluated ...
When a cross is made between homozygous dominant (AABB) and recessive (aabb) parents, the F 1 progeny will be heterozygous dominant (AaBb). This F 1 progeny of Mendelian dihybrid cross produces 4 types of gametes, namely AB, Ab, aB and ab. The progeny of F 2 generation will produce four types of phenotype and the ratio will be 9:3:3:1.
