How many chromosome has copies?
Organisms can have two copies of each chromosome, one from each parent. This is known as diploid. Other organisms, like plants, can have more than two copies of each chromosome (polyploidy). Having multiple copies of chromosomes can affect gene expression and traits in organisms.
What do mutations cause in genotype and phenotype?
Mutations can cause changes in the genotype by altering the DNA sequence. These changes can then affect the phenotype by influencing the expression of certain traits or characteristics in an organism.
How do different densities affect small organism?
small organisms have more oxgyen than big organisms
Is it easier to analyze genotype by observing phenotype in organisms with complete dominance or in organisms with incomplete dominance?
It is easier to analyze genotype by observing phenotype in organisms with incomplete dominance (also known as codominance), because in incomplete dominance the individual will show a specific phenotype for each situation, whether it is homozygous dominant, heterozygous, or homozygous recessive. For example, in flowers, such as the ones that Mendel studied, a homozygous dominant flower will be red, a homozygous recessive flower will be white, and a heterozygous flower will be pink. In complete dominance, a heterozygous will only express the dominant phenotype, as opposed to incomplete dominance, in which a heterozygous individual will express a phenotype that is representative of both of the dominant and recessive traits. Because heterozygous individuals in complete dominance express the dominant phenotype, it is hard to determine whether the genotype is homozygous dominant or heterozygous for the trait. Hope this helps!
Why do X-linked traits affect men more than women?
X-linked traits affect men more than women because men have only one X chromosome, while women have two. If a man inherits a recessive X-linked trait, he will express it since there is no second X chromosome to potentially mask the effect. In contrast, women can be carriers of the trait on one X chromosome without expressing it if the other X chromosome carries a normal allele. Consequently, X-linked disorders are more prevalent in men.
Do more-complex organisms always have more chromosome than simpler organisms do?
Yes

Name two factors that determine the phenotype of a trait?
genes
Does selection operate on the genotype or the phenotype?
Selection operates on the phenotype, which is the observable characteristics of an organism. Organisms with certain phenotypic traits that increase their fitness are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
Traits controlled by recessive alleles on the x chromosome are more common in males than in females explain why?
Males only have one X chromosome, so even if the gene on that chromosome is recessive there is no other gene that could dominate it. Females have two X chromosomes, so if the gene on that chromosome is recessive there is still a chance that the gene on the other chromosome could be dominate and override it.

What is euckaryotic?
Eukaryotic organismsare those organisms that have a well defined nuclear region and a nuclear membrane. they have more than one chromosome and the vacuols are present.
Why do X-linked traits affect men more than women?
X-linked traits affect men more than women because men have only one X chromosome, while women have two. If a man inherits a recessive X-linked trait, he will express it since there is no second X chromosome to potentially mask the effect.

Consequently, X-linked disorders are more prevalent in men.
Does Hemophilia affect men more than woman?
Yes, hemophilia is typically more common in males than in females. This is because the gene for hemophilia is located on the X chromosome, and males only have one X chromosome. In females, who have two X chromosomes, one healthy gene can compensate for the faulty gene, reducing the chances of exhibiting symptoms.
