In the spotted tulip, white flowers are dominant to yellow (gene Y), and axial flowers are dominant terminal flowers (gene T). E

ach trait is on a different chromosome. Use the Punnett Square to determine the possible offspring from a cross between two plants that are heterozygous for both traits.

Answer:

<em>9/16 A_B_ White colour, axial flower </em>

<em>3/16 A_bb White colour, terminal flower</em>

<em>3/16 aaB_ Yellow colour, axial flower</em>

<em>1/16 aabb Yellow colour, terminal flower</em>

Explanation:

Let the flower colour allele be represented by A and the flower position by B. The dominant white colour would be A while the alternate version (the yellow colour) would be a. Also, the dominant axial flower position would be B while the alternate terminal position would be b.

The Punnet's square result of crossing two plants that are heterozygous for both traits is as in the attached image.

AaBb x AaBb

Possible Offspring

<em>9/16 A_B_ White colour, axial flower </em>

<em>3/16 A_bb White colour, terminal flower</em>

<em>3/16 aaB_ Yellow colour, axial flower</em>

<em>1/16 aabb Yellow colour, terminal flower</em>

Why do many diseases such as measles occur only once in a person yet others such as colds occur more than once?

mezya [45]

Answer:

This happens because of our immune system. Our immune system keep record of every attacking microbe. It contains two type of while blood cells firstly is T cell that respond quickly to the attacking microbe. While secondly B cells that recognize those specific cells and fights them off. In addition to that B cells clones itself as memory cells for that disease and will remains in your body for years

How can the random distribution of alleles result in a predictable ratio?

levacccp [35]

Phenotypically and genotypically there are only two different ratios. If you think of a Punett square...

<span>You could say that a pea plant with the trait for the dominant color green (G) could also carry the recessive trait for yellow (g). So let's say you mate a dominant green, (Gg) with another dominant green, (Gg). You would get 1 (GG), 2 (Gg) and 2 (gg). </span>

<span>Phenotypically (as in physical traitwise), the ratio is 3:1 because you have 3 green colored peas and one yellow. </span>

<span>Genotypically (as in traitwise), the ratio is 1:2:1, because you have 1 (GG), 2 (Gg) and 1 (gg). </span>

<span>So although it's random, for any specific trait there are only 4 different outcomes.</span>

What must happen before meiosis can begin

RUDIKE [14]

Answer:

The correct answer is option C.

Explanation:

Before meiosis, DNA that is stacked into chromosomes must replicate. Before replication, the sex cell has two copies of each chromosome, one from mother, and one from father.

DNA replication takes place in the same manner as it does during mitosis. After the chromosome replication, the homologs are double in number, and each chromosome now has a homologous pair of chromosomes.

Thus, the correct answer is option C.
