Both parents would each have one dominant gene for normal pigmintation and each would have one recessive albino gene. Say P is the dominant gene and q is the albino gene. Then the parents genotype would both be Pq. Below is a Punnet Square. The child's genotype is qq

What discovery in the 1900s suppoprted mendels ideas?
The discovery of DNA in the 1950s provided strong support for Mendel's ideas on inheritance. Understanding that genes are made up of DNA and that they are passed down from parents to offspring helped to confirm Mendel's principles of heredity.
Is it true that Mendels principles apply not to just to pea plants but to other organism as well?
Yes, Mendel's principles of inheritance, such as the law of segregation and the law of independent assortment, apply to many other organisms beyond pea plants. These principles have been found to hold true in various animals, plants, and even humans, demonstrating their widespread relevance in genetics.
Circle the letter of each sentence that is true about mendels principles?
Inheritance is determined by discrete units passed down from parents to offspring. An individual receives one unit (allele) of a gene from each parent for a particular trait. Alleles can be dominant or recessive, affecting the expression of a trait in an individual. 4.Genes for different traits are inherited independently of each other.
What can be known about Mendels five-part hypothesis?
Mendel's five-part hypothesis, known as Mendel's laws of inheritance, includes the principles of segregation, independent assortment, dominance, recessiveness, and the law of uniformity. These laws explain how traits are passed on from parents to offspring, and laid the foundation for the study of genetics. Mendel's research with pea plants in the 19th century provided key insights into heredity and the transmission of genetic traits.
What was the first generation of offspring in Mendels experiment?
The first generation of offspring from a cross is called the F1 generation.
A man and a woman who are both heterozygous for normal skin pigmentation Aa produce an albino offspring AA Which of Mendels principles explains why the offspring is albino?
Dominance and Segregation
What do mendels principles apply to?
Gregor Mendel developed principles of heredity.
What letters can be used to model Mendels cross of true-breeding tall plants what true-breeding short plants in a Punnett square?
TT for the homozygous tall parent, tt for the homozygous short parent and Tt for the heterozygous offspring.
What best describes the F1 offspring of mendels two factor cross?
The F1 offspring of Mendel's two-factor cross will all display the dominant phenotype for both traits due to the dominance of the alleles. They will be heterozygous for both traits, carrying one dominant and one recessive allele for each trait.
Kind of trait that always appeared in the offspring produced in mendels first experiment?
Division.
What kind of trait always appears in the offspring produced in Mendels first experiment?
Dominant
What is the kind of trait that seem to vanish in the offspring produced in Mendels first experiment?
RECESSIVE
Why was 3 1 the ratio in Mendels F2 generation?
In Mendel's F2 generation, the 3:1 ratio observed for dominant to recessive traits arises from the segregation of alleles during gamete formation. When he crossed heterozygous parents (Tt), the resulting offspring can inherit combinations of alleles that produce three dominant phenotype offspring (TT or Tt) and one recessive phenotype offspring (tt). This reflects the principles of Mendelian inheritance, specifically the law of segregation, where each parent contributes one allele for a trait, leading to the 3:1 phenotypic ratio in the F2 generation.
Does your analysis support or refute mendels hypothesis of dominant and recessive inheritance?
You are from Kerr. The answer is on the textbook. The analysis does support the hypothesis because some of the offspring's genotype is heterozygous, as they have two different alleles. They do not have the recessive traits expressed, except in organisms that are homozygous recessive. You're so welcome.
What is a kind of trait that seemed tio vanish in the offspring produced in mendels first experiment?
reccesive
What was the second generation of offspring in mendels experience called?
F2 generation (second filial generation)
Which of Mendels principles explain why the offspring is albino?
The principle of dominance and recessiveness explains why the offspring is albino. Albinism is a recessive trait, meaning that both parents must carry at least one copy of the albino gene in order for it to be expressed in the offspring. This demonstrates how traits can be masked in one generation and expressed in the next through Mendelian genetics.
