A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.
No
The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.
Mendel proposed the concept of dominant and recessive traits, where recessive traits are masked in the F1 generation but can reappear in the F2 generation when two carriers of the recessive trait combine and show the trait. This is known as the Law of Segregation, where pairs of alleles separate during gamete formation, leading to the reemergence of hidden traits.

Alleles are pairs of genes that determine a specific trait in an organism. Each parent contributes one allele, and the combination of alleles determines how the trait is expressed. If the alleles are the same (homozygous), the trait will be expressed in a certain way. If the alleles are different (heterozygous), one allele may be dominant and determine the trait's expression, while the other may be recessive and not expressed.
Dominant and Recessive Alleles Diploid organisms typically have two alleles for a trait. When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive.
Every gene has a dominant and recessive allele, homozygous is just when a gene has either two dominant alleles or two recessive alleles.
Alleles are alternative forms of a gene that may differ in their nucleotide sequence, leading to variations in traits. Genes come in pairs, with one allele inherited from each parent, contributing to an individual's genotype and phenotype. Alleles can be dominant or recessive, influencing the expression of traits in an organism.
No
Homozygous individuals have two identical alleles for a particular gene, while heterozygous individuals have two different alleles for the same gene. Homozygotes can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygotes have one dominant and one recessive allele.
Homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes. It is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait.
The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.
The outward expression of a gene is determined by the alleles. Alleles come and pairs, and the pairings can be heterozygous or homozygous. For homozygous (both alleles are the same) phenotypes, the trait you see is the same as the alleles. For example, if both alleles are for a white flower, the flower will be white. There are different outcomes for heterozygous (one dominant allele, the other recessive) phenotypes. In complete dominance (the most common), the dominant allele is the the trait you see. For example, the flower has an allele for red (dominant) and white (recessive), it will be red because red is dominant to white. In incomplete dominance, the dominant allele is not strong enough to fully cut out the recessive so trait will be a mix of both. In the flower's case, it would be pink because white will be seen through the red. In codominance, both alleles are expressed just on different areas. The flower would have both red and white splotches.
