Models to estimate maternally controlled genetic variation in quantitative seed characters
1Department of Vegetable Crops, University of California, 95616, Davis, CA, USA.
Summary
This study introduces simple genetic models to quantify maternal effects on seed traits in plants. These models improve the estimation of genetic parameters by accounting for contributions from various maternal tissues.
Area of Science:
- Plant genetics
- Quantitative genetics
- Developmental biology
Background:
- Estimating genetic contributions to traits uses various models.
- Maternal effects, beyond embryo genotype, are often pooled and difficult to quantify.
- Existing methods for maternal effects lack precision or are overly complex.
Purpose of the Study:
- To present simple genetic models for estimating quantitative genetic parameters.
- To account for maternal effects originating from specific seed tissues.
- To improve the resolution of maternal contributions in plant breeding.
Main Methods:
- Development of novel, simple genetic models.
- Integration of maternal effects from endosperm, testa, and cytoplasm.
- Estimation of quantitative genetic parameters.
Main Results:
- The proposed models allow for the estimation of quantitative genetic parameters.
- Maternal effects from distinct seed tissues can be quantitatively assessed.
- Improved resolution of genetic contributions to seed traits.
Conclusions:
- Simple genetic models can effectively estimate quantitative genetic parameters including maternal effects.
- These models offer a more precise approach to understanding maternal contributions to seed traits.
- The findings have implications for plant breeding and genetic studies.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...

58.1K
When crossing pea plants, Mendel noticed that one of the parental traits would sometimes disappear in the first generation of offspring, called the F1 generation, and could reappear in the next generation (F2). He concluded that one of the traits must be dominant over the other, thereby causing masking of one trait in the F1 generation. When he crossed the F1 plants, he found that 75% of the offspring in the F2 generation had the dominant phenotype, while 25% had the recessive phenotype.

29.1K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

02:03Law of Independent Assortment
46.7K
While Mendel’s Law of Segregation states that the two alleles for one gene are separated into different gametes, a different question of how different genes are inherited remains. For example, is the gene for tall plants inherited with the gene for green peas? Mendel asked this question by experimenting with a dihybrid cross; a cross in which both parents are homozygous for two distinct traits resulting in an F1 generation that are heterozygous for both traits.
