Question

explain mendels monohybried progeny help of any one croos ​

Answer 1

Answer:

Monohybrid cross is a cross between two parents that have one pair of contrasting characters; for example, if pea plant with yellow seed coat is crossed with pea plant having green seed coat then in the F¹ generation all the plants produce yellow seeds.

When the plants of the F¹ are selfed the progeny or the F² generation produces Yellow seed coat and green seed coat in the ratio of 3:1 respectively.

FOR THE CROSS, PLEASE

Answer 2

please must watch this photo.. for understanding .

Example. method (1)

Explanation :-

• mendels monohybried progeny
• Monohybrid cross is a cross between two parents that have one pair of contrasting characters;
• for example, if pea plant with black seed coat is crossed with pea plant having white seed coat then in the F1 generation all the plants produce black seeds.
• When the plants of the F2 are selfed the progeny or the F2 generation produces black seed coat and white seed coat in the ratio of 3:1 respectively.

_______________ OR _______________

Example method (2)

• A cross between pure breeding tall (TT) and dwarf (tt) varieties gives all heterozygous tall (Tt) progeny in F1 generation.
• Selfing of F1 hybrid gives tall and dwarf F2 progeny in 3: 1 ratio respectively. Since allele for tallness (T) is dominant over that of dwarfism (t); heterozygous dominant genotype (Tt) gives "tall" phenotype and dwarfism is masked from being expressed. Both homozygous dominant (TT) and heterozygous dominant (Tt) exhibit "tall" phenotype while homozygous recessive genotype gives dwarf phenotype; hence phenotypic ratio is 3 tall: 1 dwarf but the genotypic ratio is 1 TT: 2 Tt: 1 tt.
• Parent generation TT x tt
• F1 generation Tt
• Selfing Tt x Tt
• F2 generation TT Tt Tt tt

{ Note :- You can write either of these two, I have put two examples here, so write the same example.}

i hope it helps you
