The gene for flower position in pea plants exists as axial or terminal alleles. Given that axial is dominant to terminal, list a

____ [38]

Answer:

A A

a Aa Aa

All the offspring have flower located at axial position

A a

A AA Aa

a Aa aa

Three offspring with genotype i,e Aa, Aa and Aa will have flower located at axial position

Only offspring with genotype "aa" will have flower located at terminal position

Explanation:

Let the allele "A" represent the characteristics of axial position of flower

Let the allele "a" represent the characteristics of terminal position of flower

Given -

"A" is dominant over "a"

F1 generation -

Two parents with homozygous genotype for both A and a are crossed . The punnet square for the cross between "AA" and "aa" is as follows -

A A

a Aa Aa

Thus the genotype of offspring is "Aa"

Since, "A" is dominant over "a", all the offspring have flower located at axial position

F2 generation-

The cross between two parents having heterozygous genotype "Aa" will take place .

The punnet square for the cross between "Aa" and "Aa" is as follows -

A a

A AA Aa

a Aa aa

Three offspring with genotype i,e Aa, Aa and Aa will have flower located at axial position

Only offspring with genotype "aa" will have flower located at terminal position

Answer correctly - 50POINTS!!!!

Dahasolnce [82]

Answer:

1) option A - 5' TAG CTG GTA 3'

2) Option C - regulates which materials enter and leave the cell

3) option B - heredity information

Explanation:

For question 1) The complimentary strand will read in opposite direction 5' to 3', and will have each base replaced by its specific base pair:

Adenine (A) replaced by Thymine (T)

Guanine (G) replaced by Cytosine (C)

Thus, the complimentary strand of 3' ATC GAC CAT 5' read as 5' TAG CTG GTA 3'

For question 2)

Cell membrane is a flexible membrane made up of proteins and lipids, and is role is to

- select the materials absorbed by the cell

- protects the cell

For question 3)

DNA stores hereditary information along its sequence in form of genes, that are passed down to offsprings, and determine their traits/behavior

Which of the four strands match the strand in the diagram by base pairing?

larisa86 [58]

Answer:

a. GGTGACT

Explanation:

An easy way to remember base pairing is to think of it as (A)pples to (T)rees, (C)ars to (G)arages. So, A pairs with T, and C pairs with G.

Hope this helps! :)
