Women gives birth to a baby boy. A few years later she gives birth to another baby boy. What is the probability that her third child will be a girl? Play your reasoning
Answers
Answer:
50 %
Explanation:
It is given that a woman gives birth to a baby boy. Her second child is also a baby boy. Now she is about to give birth to her third child. We have to determine the probability of the child to be a girl.
Here, the probability of the child to be a girl would be 50 % or 1 out of 2.
There are two possibilities and the possibilities would result a boy child or a girl child. So there are two possible outcomes and is equally likely with each child birth.
Also each child birth is an independent event, so the probability that the one results will occur do not depend on the previous births.

What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Answers
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.

Modern organisms in similar environments often have similar physical

badger, Selective pressure from similar environments over time led to
these similar
vestigial features
Ccreations,
homologous features,
analogous features,
Answers
Answer:
analogous features
Explanation:
Pressure from similar environments on the organisms over time led to these similar analogous features because of the similar environmental conditions for organisms leads to the physical features that are similar in structure and function. Analogous structures are the structures which are similar in appearance in unrelated or different organisms. These structures have similarities because they perform the same job and not because they share common ancestry.

Consider the numbers of species known to exist on Earth, including the numbers that are being discovered and
the numbers thought to be going extinct. What do these
numbers suggest about biodiversity on Earth?
Answers
Answer:
A high diversity of species is known to exist among insects and land plants; fewer species are known to exist among vertebrates, bacteria, algae, arachnids, Protists, nematodes, mollusks and crustaceans. However, much greater diversity is estimated to exist among insects, fungi, bacteria, algae, and arachnids. Vertebrates are the best-studied organisms but are relatively less diverse than other groups.
