What are responsible for directing development so that organisms resemble their parents?
Genetics - Offspring get genes from both their mother and father. These genes determine the phenotype (outer appearance) of the child, like eye color, skeletal shape, etc., and it is these things that make offspring look like their parents.
What happens when a true breeding plant self pollinate?
They will look alike (same genes)
What do chromosomes do in plants?
The chromosomes in a plant cell help the plant reproduce just like animal cells. Even though plants are both male and female they need two of them to reproduce because the sperm from one of the plant cells goes to the other plant cell and copies the chromosomes so that the offspring of the cells are exactly alike.
How does a plant that lacks nitrogen look?
Deficiency of nitrogen gives pale yellow color to the plant
What is the definition of hereditary?
Heredity: Heredity is the passing of traits to offspring (from its parent or ancestors). This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism. Through heredity, variations exhibited by individuals can accumulate and cause some species to evolve. Some common (human) hereditary traits are eye and hair color and ethnicity. The study of heredity in biology is called genetics, which includes the field of epigenetics.
What role do genes play traits from parents to offspring?
the genes play a big roll in the offspring. Genes are important because they make you look like your parents

What will help you predict what an offspring will look like?
nothing can determine what the offspring will look like except for the dominant alleles for eye color
What is the difference between a Pure tall plant and 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.

How can a new plant be different from its parent plant?
No. While the new plants will look similar to the parent plants, seeds are the result of assexual reproduction and assexual reproduction means that the offspring are all unique. In other words there will be variation in exactly the same way as children do not look exactly the same as their parents.
How does a plant that lacks nitrogen look?
Deficiency of nitrogen gives pale yellow color to the plant
When two plants produce on offspring by pollination what describes the most likely appearance of the offspring plant?
it look identical to the plant the pollen came from
What three criteria did Thomas Hunt Morgan look for in a model organism for geneic studies?
Genes are passed from their parents to their offspring. Mendel's principles apply to all organism. Genes that come from their parents are segregate from each other when gametes are formed
Which parental pair could produce females with colorblindness?
Yes. Two normal-visioned parents can produce a color blind child only if both the parents have are heterozygous. To determine the phenotypes of the parents, you will have to look at their parents.
