Answer:
genes for flower color and edge shape are linked. They do not assort independently.
Explanation:
<u>Available data:</u>
- test cross between a purple-flowered pea plant having serrated leaves and a white-flowered pea plant having smooth edges.
- serrated leaves → dominant trait
- smooth edges → recessive trait
- purple color → dominant trait
- white color → recessive trait
- F1: 4 purple-serrated:1 purple-smooth:1 white-serrated:4 white-smooth.
There are two genes involved in the cross. The expected ratios are 1:1:1:1 because we assume genes assort independently. However, we see a different phenotypic distribution. When phenotypic ratios differ from the expected ones, it means that genes are linked.
To know if two genes are linked in the same chromosome, we must observe the progeny distribution. If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. But if instead of this distribution, we observe a different one, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent

The inorganic compound is KH2PO4. Organic compounds must contain carbon and hydrogen in them to be chemically classified as organic.
Answer:
Because gametes are haploid cells they have half the number of chromosomes in a normal diploid cell. Therefore, the fly traps gamete cells will have 4 chromosomes.
Explanation:
Explanation:
Risks:
may lead to a lack of variety in plant or animal species
The nutritional value of foods can be less
Benefits:
faster than natural selection
More selective breeds / Types
