How do you determine if a tall plant is heterozygous or homozygous?
Homozygous plants have two identical copies of a single gene. Heterozygous plants have two copies of a single gene, but those copies are alleles, or different versions of that gene. The second type is heterozygous. Plants that are heterozygous for a particular gene have one copy each of two different alleles, ‘Aa’.
What is the difference between a homozygous tall plant and a heterozygous tall plant *?
Homozygous traits have two copies of the same allele. Heterozygous traits have one dominant allele and one recessive allele.
When Mendel crossed a homozygous tall pea plant with a homozygous short pea plant what was the result?
Inheritance : Example Question #6 Explanation: When a homozygous tall pea plant and a homozygous short pea plant are crossed, the next generation are all heterozygous and the dominant allele is expressed in all the plants, and the recessive trait seems to disappear.
How do you identify heterozygous and homozygous?
Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent. They do not match.
Why is the progeny always tall when a homozygous tall pea plant is crossed with a short pea plant?
a) The cross between tall and short pea plant produces the tall progeny. The tall progeny is present in heterozygous condition and the tall trait is dominant that expresses itself and suppresses the expression of the short trait.
What is homozygous tall?
A homozygous tall pea plant will have the genotype “TT” and a homozygous short plant will have the genotype “tt” because homozygous means that both alleles are identical. Since “T” is dominant over “t”, any plant with at least one “T” allele will be tall (the dominant trait), regardless of what the other allele is.
What is the difference between homozygous and heterozygous give examples of each?
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 gene of hair colour has two alleles, one of the allele codes for brown (R) and the other codes for black (r).
What is the difference between a homozygous and heterozygous gene quizlet?
Homozygous is having two identical alleles for a particular gene. Heterozygous is having two different alleles for a particular gene.
When did Mendel crossed a homozygous tall pea plant?
25\% of the heterozygous cross are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will always display the dominant trait (phenotype), because they are heterozygous.
What is the genotype of a pea plant that’s homozygous for height?
A tall, green plant is homozygous for each trait. If T is the tall allele, and G is the green allele, what is the genotype and the phenotype of this plant?…
Genotype | Definition | Example |
---|---|---|
Heterozygous | One dominant allele and one recessive allele | Tt |
Homozygous dominant | Two dominant alleles | TT |
