Complete question:

17. In the 1950’s a young woman sued film star/director Charlie Chaplin for parental support of her illegitimate child. Charlie Chaplin’s blood type was already on record as type AB. The mother of the child had type A (AO) and her son had type O blood (OO).

a. Complete a Punnett square for the possible cross of Charlie and the mother.

b. The judge ruled in favor of the mother and ordered Charlie Chaplin to pay child support costs of the child. Was the judge correct in his decision based on blood typing evidence? Explain why or why not. *refer to any Punnett squares to support your answer.

Answer:

The judge committed a mistake in his decision. There are <u>no chances</u> for this couple to have a child who has 0 blood type.

Explanation:

<u>Available data:</u>

Charlie Chaplin’s blood type was AB
The mother of the child had type A (AO)
The son had type O blood (OO).

Cross: Charlie Chaplin x The Woman

Parental) IAIB x IAi

Gametes) IA IB IA i

Punnett square) IA IB

IA IAIA IAIB

i IAi IBi

F1) 1/4 = 25% of the progeny would have IAIA genotype, blood type A

1/4 = 25% of the progeny would have IAi genotype, blood type A

1/4 = 25% of the progeny would have IAIB genotype, blood type AB

1/4 = 25% of the progeny wouldl have IBi genotype, blood type B

According to the results of the cross observed in the Punnett square, there are no chances for this couple to have a child who has 0 blood type.

Blood type 0 can only be produced by two recessive alleles i, one inherited from each parent. The mother could provide the recessive allele because she is IBi, but Chaplin could not pass to his progeny any recessive allele.

The judge committed a mistake in his decision.

Write a paragraph explaining how genetic variation, reproductive strategies and environmental pressures have impacted the surviv

Andreas93 [3]

Answer: Genetics and Pressures

Explanation:

For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.

Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.

Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.

What happens to ordinary plants (not C 4 or CAM) when stomata close?

Rom4ik [11]

As humans plants also need oxygen to breathe they only take in carbon dioxide to do photosynthesis.So they wont do photosynthesis at night and so they only need to breathe. even though their stomata are closed at night some oxygen can go inside. and this is how plants breathe when their stomata are … Enzymes change carbon dioxide to glucose.

Describe some events that could start primary succession and list the succession of plant communities in primary succession.

Bingel [31]

Primary succession occurs when a natural disaster like an EQ, volcanic eruption, or flood, occurs to an area where there is no plant or animal life. The first organisms to appear are lichens, which over a long period of tome, will begin to form soil.

Color in McIver beetles is determined by two alleles at one gene locus. McIver beetles must have a heterzygous genotype (genotyp

seraphim [82]

Answer: The frequency of brown beetles is 0.32.

Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:

1 - 0.8 = 0.2

In Hardy-Weinberg principle,

$p^{2} + 2pq + q^{2} = 1$

2pq represents the frequency of heterozygote individuals, so:

genotype A1A2 = 2*0.8*0.2 = 0.32.

Thus, the frequency of brown beetles (A1A2) in the population is 0.32.
