Answer:

well with out it we won't understand dna

but heres the scientific answer

Explanation:

DNA replication allows for organisms to be reproduced from the parent.

After a sperm (from male) and egg (from female) cell have combined, they immediately start to divide. At this point, the cell is called a zygote.

In order for the cells to divide, they need DNA from the mother. They don't steal it. They just replicate it. For a cell to use DNA, it needs to be in the form of a chromosome, a tightly-packed DNA structure

DNA replication allows for organisms to be reproduced from the parent.

Pea seed color exists as green or yellow. We might say that "yellow" is an example of a (an)_ for seed color

LiRa [457]

Answer:

b. allele

Explanation:

An allele is a variant form of a gene. In this problem, there is one gene (that determines seed color) with two possible alleles (green and yellow).

<u>The other options are wrong because:</u>

The genotype is the combination of alleles an individual has.

The karyotype is an individual's collection of chromosomes, paired and ordered.

A homozygote individual has the same alleles for a particular gene.

A heterozygote individual has different alleles for a particular gene.

) Consider a pea plant- it has a gene controlling seed color- yellow Vs green; another gene controlling seed texture-smooth Vs w

lana [24]

Answer:

Yellow smooth - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1

Explanation:

Let the green color of the seed be depicted by "G" and the yellow color of the seed be depicted by "g"

Let the smooth the seed be depicted by "R" and wrinkled seed be depicted by "r"

F1 cross -

true breeding smooth green plant ( RRGG) and true breeding wrinkled yellow (rrgg)

F1 gamete will be RG, RG, rg, rg

F1 offspring will be RrGg , Thus all F1 offspring will be heterozygous smooth and yellow.

Thus, R is dominant over r and g is dominant over G

F2 Generation –

RrGg x RrGg

Gametes will be RG, Rg, rG, rg

RG Rg rG rg

RG RRGG RRGg RrGG RrGg

Rg RRGg RRgg RrGg Rrgg

rG RrGG RrGg rrGG rrGg

rg RrGg Rrgg rrGg rrgg

R is dominant over r and g is dominant over G

Genotypes are –

RRGG - 1 (Smooth Green)

RRGg-2 (Smooth yellow)

RrGG-2 (Smooth Green)

RrGg-4 (Smooth yellow)

RRgg- 1 (smooth yellow)

Rrgg – 2 (Smooth yellow)

rrGG – 1 (wrinkled Green)

rrGg – 2 (Wrinkled yellow)

rrgg – 1 (wrinkled yellow)

Yellow smooth - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1
