Question

Three plant genes, A, B, and C, are linked and occur in the following order. Genetic distances are given as map units (m.u.):

A________10 m.u.______B_____0 m.u.__C

The genes underlie the following phenotypes:

A/_ = blue flowers, a/a = white flowers

B/_ = tall stems, b/b = short stems

C/_ = green leaves, c/c = red leaves

You cross two individuals with the following genotypes:

AbC/AbC x aBc/aBc

If you self the resulting F1 the proportion of the offspring that will have white flowers, short stems, and green leaves is (Provide the answer as a decimal number with 4 decimal places):

Answer 1

Solution Hello, today we are to discuss about a are for flower. 'B' allele codes going genetic related question ohn here it is said the A, B and genes dinked it allele codes for blue fe blue flowers and a' allele codes for white tall stems and of allde for short stem. Ĉ allele for green leaves and i allede for red leaves. o Two individuals were crossed and their genotypes A Abbcc and aaBbul for une are

F2 offsprings? et > Blue flowers, green tall stem and leaves 7 27 B7 while flowers, short stem and red leaves 1 C7 white leaves 9 tall stem and flowers, green leaves - 3 Dy white flowers, short stem and green E-) Blue flowers, shost stem and leaves 9 short stem and red leaves 3 G-7 Blue flowers, tall stem and red leaves > 9 tall stem and red leaves 3 green F7 Blue flowers, H) white flowers, tall stem

and Proportion of offspring with white flowers, short stem green leaves are Yoq are produced in this cross. Total was 64 offsprings And in this 64 offsprings, only I afspring o So the proportion of the offspring white flower, short stem short stem and sed leaves. is of 64 0.0156 Thank you
