Only sex-linked recessive traits on the X sex chromosome are more common in males. This is because males receive only one X chromosome, so they cannot be heterozygous for a trait on the X chromosome. Females inherit two sex chromosomes, so they can be heterozygous, receiving both a dominant and a recessive allele on the X chromosomes.

What is the phenotype of a purebred recessive?
A recessive trait is known as the characteristic that is the outward expression of the gene. Recessive traits can be masked by dominant traits but are still present if the gene is present in the organism.
How would an embryo traits change if one of the parents were recessive for all the traits while the other was heterozygous?

What symbols do scientists use represent dominant and recessive genes?
Usually, you would use capital letters for dominant traits (A), and lowercase for recessive (a)
For a codominant traiit do the offspring of identical parents always look like the parent why?
No, the offspring of identical parents would not always look like the parents because everyone has dominant and recessive traits, where the recessive traits do not show but is still in DNA. That said, recessive traits not shown in parents can be passed on as dominant traits to offspring - making offspring not always identical to its parents. (this is also called genetic variation)
What are traits that are hidden called?
Recessive traits can be hidden if the organism inherits one dominant and one recessive allele (i.e. is heterozygous) for a gene. If a heterozygous organism mates with another heterozygous organism for the same trait, the recessive trait may be expressed in their offspring, which would mean that the offspring inherited two recessive alleles, one from each parent.
Why are recessive disorders more common than dominant disorders?
dominant traits show up in the first generation so any disorders have a 50% percent chance of showing up in offspring. recessive traits skip a generation therefore any diseases would have on a 25% chance.

Why do recessive trail are more common in some cases?
They're not necessarily, but they can be. When a recessive trait is more common, it likely because it was advantageous to have that trait so the species evolved to have more of it in the gene pool. Also, since dominant traits are expressed over recessive traits, natural selection has more of an effect on them.

What are some examples of recessive traits?
If you have 2 parents which have a history of brown eyes in their family and you got blue eyes this would be considered a recessive trait.
If Gregor Mendel would have not used true bleeding plants would he have had discovered dominant and recessive traits?
No. At least not him.
Can 4 recessive genes make a dominant gene?
no you would have a Dihybrid gene with two traits

What type of letter do you use to represent a dominant trait?
Capital letter such as R for dominant and r for recessive trait
What kind of trait is expressed when two different genes from the same trait are present?
It depends on the gene in question, and the type of dominance of the trait.For monogenetic traits (those controlled by a single gene), the dominant trait(s) will be expressed when two different alleles are present.For example, if B leads to black fur and b leads to white fur:Complete dominance would result in a rabbit with Bb having black fur.Incomplete dominance - Bb would result in grey furCodominance - Bb would result in black and white patches/spots/etc.
