What does the term autosomal refer to quizlet?

What does the term autosomal refer to?

“Autosomal” means that the gene in question is located on one of the numbered, or non-sex, chromosomes. “Dominant” means that a single copy of the disease-associated mutation is enough to cause the disease.

What is an autosomal trait quizlet?

autosomal trait. the gene for the trait is localized to chromosomes 1-22(the autosomes) rather than being sex-linked (on the X or Y chromosome) or mitochondrial. monogenic or Mendelian Trait. produced by a single gene.

What is autosome quizlet?

Autosome. any chromosome that is not a sex chromosome. Egg. an oval or round object laid by a female bird, reptile, fish, or invertebrate, usually containing a developing embryo.

What is autosomal inheritance?

Autosomal dominant inheritance is a way a genetic trait or condition can be passed down from parent to child. One copy of a mutated (changed) gene from one parent can cause the genetic condition. A child who has a parent with the mutated gene has a 50% chance of inheriting that mutated gene.

What do the autosomes determine?

Autosomes differ from sex chromosomes, which make up the 23rd pair of chromosomes in all normal human cells and come in two forms, called X and Y. Autosomes control the inheritance of all an organism’s characteristics except the sex-linked ones, which are controlled by the sex chromosomes.

What are Allosomes and autosomes?

Autosomes are homologous chromosomes i.e. chromosomes which contain the same genes (regions of DNA) in the same order along their chromosomal arms. The chromosomes of the 23rd pair are called allosomes consisting of two X chromosomes in most females, and an X chromosome and a Y chromosome in most males.

What are autosomal chromosomes?

An autosome is any of the numbered chromosomes, as opposed to the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes (the X and Y). Autosomes are numbered roughly in relation to their sizes.

What are autosomal recessive traits?

Autosomal recessive is one of several ways that a trait, disorder, or disease can be passed down through families. An autosomal recessive disorder means two copies of an abnormal gene must be present in order for the disease or trait to develop.

What is chromosome theory of inheritance?

Boveri and Sutton’s chromosome theory of inheritance states that genes are found at specific locations on chromosomes, and that the behavior of chromosomes during meiosis can explain Mendel’s laws of inheritance.

What are zygotes quizlet?

zygote. The fertilized egg, which is diploid, that results from the union of haploid gametes (sperm and egg) during fertilization.

What is a embryo quizlet?

embryo. a developing human during the early stages of development; the term embryo is used from the middle of the second week following fertilization until the end of the eighth week. fetus. a developing human from the ninth week following fertilization to birth; in Latin fetus means “offspring”.

Is a zygote a haploid cell?

A zygote is a fertilized eukaryotic cell. … In humans, the male gamete is the sperm cell and the female gamete is the ovum (also called egg cell). Both of them are haploid (n). Their union will result in a zygote that is diploid (2n) and by a process called fertilization.

What does autosomal dominant mean Punnett Square?

A) Autosomal dominant inheritance: A mother with an autosomal dominant mutation has children with a father who is normal. They have 50% chance with each pregnancy of having a child (boy or girl) affected by the disease and a 50% chance having a child (boy or girl) unaffected. B)

What are in chromosomes?

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
