How do scientists use the fossil record

RideAnS [48]

The Fossil Record. Fossils provide evidence that organisms from the past are not the same as those found today, and demonstrate a progression of evolution. Scientists date and categorize fossils to determine when the organisms lived relative to each other.

1. If the frequency of two alleles in a gene pool is 90% A and 10% a, what is the frequency of individuals in the population wit

Illusion [34]

Answer: 0.18

Explanation:

For the alleles, the percentage distribution of each is 'A' (90% = 0.9)

While 'a' (10% = 0.1)

Hence, 0.9 and 0.1 are the respective frequencies of each allele

Now, apply Hardy-Weinberg Equilibrium equation, where heterozygotes are represented by the 2pq term.

Therefore, the number of heterozygous individuals (Aa) is equal to 2pq which equals

2 × 0.9 × 0.1 = 0.18

Thus, the frequency of heterozygote is 0.18, while the percentage distribution in the population is 18%

9. Consider the below Punnett square cross. Explain how you could use it to determine which parent

kogti [31]

Answer: The father determines the biological sex of a baby

Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.

What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.
