marta [7]1 year ago
6 0

Plant cells have plastids and larger vacoule and they also have tough cellulosic cell wall outer to cell membrane as a covering.

Animal cells don't have cell wall rather they have cell membrane as it's outermost covering and they have smaller vacuoles.They also don't have plastids.They have centrosome which is not found in plant cells.

1. Explain how the traits of an organism are related to the genes in DNA.
viktelen [127]

Genes in DNA or responsible for the traits an organism has. This is caused by Dominant and Recessive Traits. Remember that Genotypes are the genetic letters such as RR, Rr, and rr. Phenotype is physical traits.

Dominant Traits are more likely or always show in the offspring. The Dominant Genotype uses Capital letters such as RR.

Recessive Traits are less likely to show up. Their Genotype use lower case such as rr. Now genotypes of Rr have one dominant trait and one recessive trait. If the dominant trait was black fur and the recessive white fur, the offspring will be black fur because dominant traits overpower the other.

To understand how to know if an organism will have Dominant or Recessive Genes, you have to use something called a Punnet Square. Lets imagine 2 parents both have the genotype Rr. R is Black fur and r is white fur. As you can see from the chart, 3 of 4 boxes have Rr and 1 rr. Since there is a Dominant Trait with a Recessive, they will show a Dominant Phenotype, or Black fur. This has 3/4 chance and a 1/4 chance for white fur in the offspring.

A chromosomally XY fetus has a completely functional SRY gene and develops fully functional testes that produce both testosteron
ale4655 [162]

Answer:

Neither the Wolffian ducts nor the Mullerian ducts will develop

Explanation:

SRY gene is the gene is located on the Y chromosome and it is responsible for the development of testes.

MIS is Anti-Müllerian hormone which has the role to prevent the development of  Müllerian ducts (they develop into female internal genitalia).

Androgen insensitivity syndrome is a disorder characterized by unfunctional androgen receptors. If androgen receptors are not working properly,  the Wolffian ducts (they develop male internal organs) will not develop.

So, with MIS and withandrogen insensitivity syndrome, this fetus will not develop neither the Wolffian ducts nor the Mullerian ducts.
