Segregation. The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells. <span>The segregation of gene variants, called alleles, and their corresponding traits was first observed by Gregor Mendel in 1865. Mendel was studying genetics by performing mating crosses in pea plants. He crossed two heterozygous pea plants, which means that each plant had two different alleles at a particular genetic position. He discovered that the traits in the offspring of his crosses did not always match the traits in the parental plants. This meant that the pair of alleles encoding the traits in each parental plant had separated or segregated from one another during the formation of the reproductive cells. From his data, Mendel formulated the Principle of Segregation. We now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.</span>
Answer:
<h3>
Constant movement around the sun</h3>
Explanation:
We have different seasons because of the earth’s constant movement around the sun. The closer a place on earth is to the sun, the warmer it will be. The farther away it is, the colder it will be.
<h3>Brainiest?</h3>
<h2>I BELIEVE YOUR ANSWER IS FALSE </h2>
In that situation the risk of cord compression during the child birth. Serious umbilical cord problems can result in brain damage or the death of baby.
Umbilical cord occurs when the baby weight on the placenta or the vaginal walls put pressure on the cord during pregnancy labor or delivery. Cord compression during pregnancy is common problem. Sing of umbilical cord compression may include less activity form the bay observed as a decrease in movement or an irregular heart beats.
Umbilical cord compression is a medical term used to describe a condition in which a baby's umbilical cord becomes flattened by pressure of the baby.
