Question

A pea plant heterozygous for pod shape and flower colour was selfed and total 512 seeds were obtained. What will be the total number of seeds with inflated pod and white coloured flowers?

Answer 1

j don't know

sorry ☹☹☹☹

Answer 2

Dihybrid cross for two heterozygous characters

Explanation:

• The genotypic ratio of Mendelian dihybrid cross for the pea plant with 2 heterozygous characters is given by 1:2:2:4:1:2:1:2:1 .
• Here, there are 2 traits , namely , pod shape and flower color which means there will be 4 seeds that are heterozygous for the 2 traits.
• In a single dihybrid cross , 4 alleles or 4 seeds are heterozygous for the 2 characters or traits.
• This implies that 25% of the total seeds produced. Therefore , in this case also, 25% of total 512 seeds , which will be 128 in number.
• Hence , 128 seeds will be produced with inflated pod and white color flowers.
