Draw a Punnett square for a monohybrid cross between A) two homozygous parents (one dominant and on recessive), and B) a heterozygous dominant parent and homozygous recessive parent

Solutions

Expert Solution

ANSWER :----

MONOHYBRID CROSS -

  • When we consider the inheritance of one character at a time in a cross this is called monohybrid cross.

PUNNET SQUARE -

  • The representation of generations to analyse in the form of symbols of squares . male gametes lies horizontally and female gametes lies vertically.

punnet square ask in question is drawn in following -

(A)

  • when homozygous dominant parent is cross with a homozygous recessive parent ,then dominant and recessive character show in offsprings in the ratio of 3:1 respectively.

(B)

when heterozygous dominant parent is cross with homozygous recessive parent ,then dominant and recessive characters are shown in equal ratio (1:1) in offsprings .

1. Use a Punnett’s squares to show a monohybrid cross between pure breeding parents of tall (T) and dwarf (t) pea plants. The tall trait is dominant and thus is represented by the uppercase letter “T”. The dwarf trait is recessive and is represented by to lowercase letter “t”. 2. You have a pea plant with purple flowers but you are unsure of it’s genotype. Since purple flowers is the dominate trait (P), while the recessive trait is white flowers...
