Question

In garden peas, the allele for tall plants (T) is dominant over the allele for dwarf plants (t). A true-breeding tall plant is bred with a true-breeding dwarf plant to produce heterozygous tall plants. The F1 heterozygotes then self-fertilize to yield F2 offspring. Complete the Punnett square for this monohybrid cross using the F1 gametes with the appropriate genotype and placing the correct F2 genotype/phenotype combination in the Punnett square.Male gamete TT Tall Tt Tall Female gamete Tt Tall tt Dwarf For each of the following. determine the probability that a child will be affected with the given condition.Consider the following genotypes and phenotypes:BB, Bb, yellow(normal) urinebb, beeturia(red urine after eating beets)HH, Hh, colored eyelidshh, normal eyelidsEE, Ee, brachydactyla(short fingers)ee, normal fingers1. If a man and woman both have a genotype Ee, then what is the probability that their child wii have normal fingers?2, If a man has a normal urine and genotype Bb and woman has beeturia and genotype bb what is the probability that the child will have beeturia fingers?3. What is the probability that their child will have colored eyelids?4. What is the probability that their child will have colored and beeturia eyelids?

Answer 1

Step-by-step explanation:

TT ×tt

I

Tt Tt Tt Tt

Where Tt Tt Tt TT are the genotype for the first filial generation.

To generate the 2nd filial generation, we self the 1st generation.

Tt × Tt

I

TT Tt Tt tt

We have TT Tt Tt tt as the second filial generation.

If a man and a woman both have Ee the probability that the child will have normal finger is 1/4

Ee × Ee

I

EE Ee Ee ee

Where EE, Ee is brachydactly and ee is normal finger.

When a man with normal eye is crossed with a man with beeturia the probability of having a child with beeturia 2/4

Bb × bb

I

Bb bb Bb bb

Where BB Bb is normal eye and bb is beeturia

When a man with colored eye lid HH is crossed with normal eyes lid hh the probability of having a child with color eyes lid is 1

HH × hh

I

Hh Hh Hh Hh

Where Hh represent normal eyes lid
