What is a plant that has two dominant genes or two genes called?
a homozygous
If a pea plant has two alleles YY. what is its genotype?
The genotype of a pea plant with two alleles YY is homozygous dominant. This means that both alleles for the trait in question are the same and dominant. In this case, the plant will express the dominant trait associated with the YY genotype.
A plant with two recessive genes for height is crossed with a plant with one dominant and one recessive gene for height What genes will their offspring have?
hh X Hh You get two recessives; hh and hh and two heterozygous plants; Hh and Hh
What are the different stages of a plant's life cycle?
The plant cycle consists of 5 main processes. The uvula, The morph the Susin, phinosis and the Lisha. They each have a specific process and each do something to help and at the same time destroy the Plant.
When is a character said to be dominant?
Hello there, Dominant and recessive traits can be tested by reproduction. For example, if I was to grow a tall pea plant and a short pea plant that are true breeds, and if I was to cross pollinate them to form a hybrid pea plant, the new pea plant offspring would exhibit the dominant trait out of tall and short (In this case tall). When reproduction occurs, two alleles for a given gene will be introduced, and only the dominant trait will be used and exhibited by the offspring. That way, if we want to determine whether a trait is dominant, we will need to test through reproduction. Hope this helps!
What is the dominant phase of the bryophyte life cycle?
Bryophytes or Moss plants life cycle goes with two stages. The two stages are the haploid (gametophyte) and the diploid (sporophyte) which is the dominant stage.
What are the two major stages of a plant life-cycle?
The Sporophyte stage and the gametophyte stage
Explain the stages in the life cycle of a fern?
A fern's life cycle alternates between two distinct stages: the sporophyte and gametophyte. The sporophyte stage is the dominant phase, where it produces spores through meiosis. These spores germinate into tiny gametophytes, which produce eggs and sperm. Fertilization of the egg by the sperm results in a new sporophyte plant.
What are the to stages of moss life cycle called?
The two stages of a moss life cycle are the gametophyte stage and the sporophyte stage. The gametophyte is the dominant and photosynthetic stage, while the sporophyte is short-lived and dependent on the gametophyte for nutrients.
How many stages are in the life cycle of a seed plant?
The life cycle of a seed plant typically consists of two main stages: the sporophyte stage (where the plant produces spores through reproductive structures like flowers or cones) and the gametophyte stage (where the plant produces gametes through the process of fertilization).
When a plant inherits two dominant alleles it looks like what?
wha- dominant? alleles?
What is a plant that has two dominant genes or two genes called?
a homozygous
What kind of plant has one dominant gene and two recessive gene?
A plant that exhibits this genetic inheritance pattern would have a heterozygous genotype, where one allele is dominant and the other two alleles are recessive. This would result in the dominant trait being expressed in the plant's phenotype.
How would you describe the plant life cycle?
The plant life cycle is divided into two main stages: the sporophyte stage and the gametophyte stage. The sporophyte stage begins when a seed germinates and grows into a mature plant that produces spores. These spores develop into gametophytes, which produce gametes (egg and sperm) that combine to form a new sporophyte plant. This cycle repeats itself to perpetuate plant growth and reproduction.
How many life cycles do seals have?
Two stages
What is the difference between a pure tall plant and a hybrid tall plant?
Pure TraitsPure traits can be either recessive or dominant. Pure traits may have two dominant genes or two recessive genes. For example, a pea plant may have two genes for tallness, which is dominant trait in pea plants. This plant is homozygous plant with a pure dominant trait for tallness. All of the offspring from this plant will be tall. A pea plant with two genes for shortness is also a pure organism. However, shortness in pea plants is a recessive trait. This plant is a homozygous plant with a pure recessive trait for height. The offspring from this plant will be short if it pollinates with another plant that has two genes for shortness. If this plant pollinates with a tall pea plant, the tall dominant gene will mask or cover up the recessive gene for shortness. Both plants are homozygous or pure plants; one is a pure dominant pea plant, the other is a pure recessive pea plant.Hybrid TraitOrganisms that have two unlike genes for a certain trait are called hybrid. A pea plant with one recessive gene for shortness and one dominant gene for tallness is a hybrid for that trait. A hybrid is called heterozygous, as it has two different alleles. The offspring from a pure tall pea plant, cross-pollinated with a pure short pea plant, will result in a heterozygous plant for tallness. No organism has all dominant or all recessive genes. An organism may be pure in certain traits and hybrid others. Remember, that a dominant trait in one kind of organism may be a recessive trait in another organism.
A plant with two recessive genes for height is crossed with a plant with one dominant and one recessive gene for height What genes will their offspring have?
hh X Hh You get two recessives; hh and hh and two heterozygous plants; Hh and Hh
