2017年4月27日 · Heterozygous is a description of the genotype, or combination of alleles present in an organism. The genotype gives rise to the phenotype. Depending on the different relationships between alleles, different phenotypes are created in a heterozygous individual.

2019年11月27日 · In diploid organisms, heterozygous refers to an individual having two different alleles for a specific trait. An allele is a version of a gene or specific DNA sequence on a chromosome. Alleles are inherited through sexual reproduction as the resulting offspring inherit half of their chromosomes from the mother and half from the father.

Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous. For example, assume the gene of hair colour has two alleles, one of the allele codes for …

2021年8月17日 · An organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for a particular trait is considered heterozygous for that trait. In plant and animal breeding, such organisms can be called homozygotes and heterozygotes. What does homozygous mean?

Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

2021年9月22日 · When P plants with contrasting traits were cross-fertilized, all of the offspring were heterozygous for the contrasting trait, meaning their genotype had different alleles for the gene being examined. For example, the F 1 yellow plants that received a Y allele from their yellow parent and a y allele from their green parent had the genotype Yy.

2020年2月25日 · Heterozygous refers to having different alleles for a particular trait. When alleles are heterozygous in complete dominance inheritance, one allele is dominant and the other is recessive. The genotypic ratio in a heterozygous cross …

Mendel studied inheritance using the garden pea, Pisum sativum. This species naturally self-fertilizes, such that pollen encounters ova within individual flowers. The flower petals remain sealed tightly until after pollination, preventing pollination from other plants. The result is highly inbred, or “true-breeding,” pea plants.

When P plants with contrasting traits were cross-fertilized, all of the offspring were heterozygous for the contrasting trait, meaning their genotype had different alleles for the gene being examined. For example, the F 1 yellow plants that received a Y allele from their yellow parent and a y allele from their green parent had the genotype Yy.

In a homozygous plant, a gene pair (alleles) contains two identical genes controlling similar trait of a character. In heterozygous plant, a gene pair (alleles) contains two different genes controlling different traits of a character in an organism.
