Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes. This picture of the human chromosomes lined up in pairs is called a karyotype.

Of the 23 pairs of chromosomes, the first 22 pairs are called "autosomes." The final pair is called the "sex chromosomes." Sex chromosomes determine an individual's sex: females have two X chromosomes (XX), and males have an X and a Y chromosome (XY).

"what advantage do organisms that reproduce sexually have over organisms that reproduce asexually?"
makvit [3.9K]
Organisms that reproduce sexually have greater genetic and thus characteristic variations, and so, are able to withstand more selection pressures if they so happen to change or become greater. This increases the chances of survival for that species itself.

Organisms that reproduce asexually are genetically identical to each other. They are unlikely to withstand any changes in selection pressures.

Hope this helps! :)

What is the probability that the offspring will have purple flowers?; What is the phenotypic ratio for the purple flowers?; What
Luda [366]

The probability that the offspring will have purple flowers is 50% chance Let's go ahead and assume that:

The allele A corresponds to the color of flowers.

As a result, A would stand in for the alternate white hue and represent the dominating purple color.

According to the aforementioned hypotheses, a white flower would have the genotype aa while a heterozygous purple blossom would have the genotype Aa.

Now let's connect the two flowers:

Aa x aa

Aa Aa aa aa

The genotypes, phenotypes, and odds of the offspring would be as follows based on the cross's outcomes:

Purple color, Aa; 1/2

white flower color, aa, 1/2

In other words, there is a 50% chance that the cross will result in offspring with the flower colors purple (genotype, Aa) and white (genotype, aa).
