A sex cell is, by definition, a male sex cell or a female sex cell. Both are 1N and each contains half the genetic material of the parent that produced the cell. Parental traits are not combined until fertilization has occurred.
If parents supply different alleles for a certain trait to their offspring, the offspring are described as heterozygous for that trait. This means they possess two different alleles, one inherited from each parent. In contrast, if the offspring received the same allele from both parents, they would be termed homozygous for that trait. The expression of the trait may depend on whether the alleles are dominant or recessive.
If an organism is homozygous for a certain trait, it means that it has two identical alleles for that trait, either both dominant or both recessive. This indicates that both parents contributed the same allele for that trait. Consequently, at least one of the parents must have also been homozygous for that allele or heterozygous, carrying the same allele. This genetic uniformity suggests that the trait is consistently passed down from the parents to the offspring.
A diploid organism with two identical alleles for a trait is referred to as homozygous for that trait. This means that both copies of the gene (one inherited from each parent) are the same, resulting in a uniform expression of that trait. For example, if the trait is flower color and both alleles are for red flowers, the organism will consistently produce red flowers.
When the alleles present for a trait are the same, the genes are called homozygous. This means that both alleles for a particular gene are identical. Homozygous individuals can have either two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive).
When an individual has two different alleles for a trait, it is referred to as being "heterozygous" for that trait. In contrast, if both alleles are the same, the individual is termed "homozygous." Heterozygosity can influence the expression of traits, particularly in cases involving dominant and recessive alleles.
The alleles for a given trait are inherited from an individual's parents.
If parents supply different alleles for a certain trait to their offspring, the offspring are described as heterozygous for that trait. This means they possess two different alleles, one inherited from each parent. In contrast, if the offspring received the same allele from both parents, they would be termed homozygous for that trait. The expression of the trait may depend on whether the alleles are dominant or recessive.
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.

Both of the alleles must be recessive. The trait expressed is a recessive trait.
A diploid organism with two identical alleles for a trait is referred to as homozygous for that trait. This means that both copies of the gene (one inherited from each parent) are the same, resulting in a uniform expression of that trait. For example, if the trait is flower color and both alleles are for red flowers, the organism will consistently produce red flowers.
A trait that appears only when both alleles are present is called a recessive trait. In this case, the trait is masked when the dominant allele is present, but becomes visible when two copies of the recessive allele are inherited.
The term for a genetic condition where both alleles for a particular trait are different from each other is called heterozygous.
When the alleles present for a trait are the same, the genes are called homozygous. This means that both alleles for a particular gene are identical. Homozygous individuals can have either two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive).
