You asked: Which of the following is a correct definition of autosomes quizlet?

Autosome. any chromosome that is not a sex chromosome. Egg.

Which of the following is a correct definition of autosomes?

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 is the definition of an autosome quizlet?

autosome. A chromosome not directly involved in determining the sex of an organism; in mammals, for example, any chromosome other than X or Y. diploid. Containing two sets of chromosomes (pairs of homologous chromosomes) in each cell, one set inherited from each parent; referring to a 2n cell. haploid.

Which of the following is a correct definition of gametes quizlet?

Gamete. A sex cell that contains the haploid of chromosomes. Haploid. The number of chromosomes in a gamete of an organism.

Which of the following is a correct definition of sister chromatid quizlet?

Which of the following defines sister chromatid? two identical copies of a chromosome that are attached at the centromere. You just studied 122 terms!

What is meant by autosomes and allosomes?

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 is the role of autosomes?

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 is the difference between autosomes and chromosomes quizlet?

Autosomes= chromosomes that don’t carry any genes that determine the sex of the individual. Sex chromosomes= carry sex-determining genes (but may also carry many other genes that have nothing to do with sex).

What is the definition of phenotype quizlet?

phenotype. the physical appearance of an organism based on the genotype (genes) pure. obtained from a cross with hybrid organisms; homozygous.

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.

Which of the following is a correct definition of gametes?

Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.

Which of the following is the correct definition of a diploid cell?

Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid.

Which of the following is the correct definition of haploid?

Haploid describes a cell that contains a single set of chromosomes. … The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23. Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells.

Which of the following is a correct definition of sister chromatid?

A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be ‘one-half’ of the duplicated chromosome. A pair of sister chromatids is called a dyad.

Which of the following is a correct definition of homologous chromosomes quizlet?

Homologous chromosomes have the same genes as each other, in the same sequence, but not necessarily the same alleles of those genes.
