They are sex-linked genes.
Traits :)
Sex-linked traits have alleles that are passed from parent to child on a sex chromosome.
These alleles are called sex-linked alleles or traits.
A parents sex chromosomes hold DNA. A parents DNA is passed onto the child.
Sex-linked traits have alleles that are passed from parent to child on a sex chromosome.
Alleles
Each parent gives a baby 23 pairs or 46 chromosomes to the offspring
Only half of each parent's alleles are passed to their children. This means that parent 1 who is Aa at one gene locus will only pass A or a on to each offspring. Parent 2 may be AA, aa or Aa and will also only pass one allele on to each offspring.
In humans, 46. 23 are passed from each parent to their child.
No. Only 1 allele each can be passed down from each parent, so it is impossible for the child to have 2 dominant alleles if 1 parent has blood group 0.
In humans, each parent contributes 23 chromosomes.In general, each parent of any species contributes the haploid number of chromosomes, which is the number of chromosomes in a single set of chromosomes.
The short answer is YES. To explain as simply as possible; Each of us inherits a set of genes from each parent, a set of alleles from each parent; in the case of blood type, the alleles that may be present at the site on the chromosome responsible for blood type may be either A,B, or O (O actually being the absence of A or B). In the above question, if one parent's alleles are A and O (remember, everyone has two alleles), their blood type is A; if the other parent's alleles are B and O, that parent types as B. If their child inherits the "O" allele from each parent, that child will be type O.
Traits can be classified as autosomal dominant or recessive. A child receives alleles from each parent, a dominant trait requires one allele and a recessive requires both.
