Answer and Explanation:
Typically, sea turtles lay around 110 eggs per clutch. However, only a small fraction of the hatchlings survive to reach the ocean. Subsequently, an even fewer number are able to produce their own young.
- Overpopulation
All zebras possess stripes, yet no two zebras exhibit identical stripe patterns.
-Variation
A lemur species named aye-ayes feature extended, slender middle fingers that enable them to probe into tree crevices to extract insects for food.- Adaptation
The method is cross-pollination, achieved by utilizing parents with distinct traits.
Gregor Mendel studied pea plants and formulated the foundational principles of heredity. He coined the terms dominant and recessive to describe traits, based on his experiments. He practiced cross-pollination, which involves mating parents that exhibit different traits. For instance, he crossed a plant bearing green peas with another showcasing yellow peas (two contrasting traits) and examined the inheritance of these traits in subsequent generations.
Answer:
The correct answer is -
a. - as the distribution of the phenotype diminishes
b. -cross sunflowers exhibiting the greatest phenotypic variance
Explanation:
Artificial selection refers to the practice of breeding plants or animals for particular desired traits by consciously choosing which individuals reproduce.
-Variance indicates how individual traits differ from the average characteristics of the species or how they deviate from the mean, demonstrating the degree of measurement differences.
-If the distribution remains unchanged, variance indicates no variation. However, if the spread indicates a range change in measurements, the variance will also change.
During step 3, chromosomes switch genetic information.
Clarification:
Meiosis is a form of cell division occurring in gamete formation. This process consists of two main stages - meiosis I and meiosis II.
Within meiosis I, events such as crossing over and independent assortment occur, leading to the exchange of genetic traits between pairs of homologous chromosomes and the division of these chromosome pairs. Therefore, the two cells generated from meiosis I will be genetically distinct. Step 3 illustrates the crossing over that happens during prophase 1 of meiosis I. Consequently, this results in genetic variation among offspring.
